`ReadWriteLock` and `AsyncReadWriteLock` (the SQLite-backed reader/writer lock) remove their private `.filelock-*` link directories with `shutil.rmtree` (a recursive delete) on a remembered path. They do not check that the path still names the directory they created. This happens on the hard-link ro

On Windows, `ReadWriteLock` and `AsyncReadWriteLock` (the SQLite-backed reader/writer lock) connect SQLite to the lock database by its path, in every directory. SQLite derives three side files from that path: ` -journal`, the rollback journal (pages saved to undo an interrupted write); ` -wal`, the

On Windows the soft locks (`SoftFileLock`, `MarkerSoftFileLock`, `SoftFileLease`, their async forms, and a `FileLock` that fell back to a soft lock) read their marker by path. The marker is the lock file whose presence says a process holds the lock. Each `acquire()` attempt that finds a marker opens

## Summary The app-data seeder can leave an environment linked to temporary package files that virtualenv deletes when creation finishes. The environment-variable and configuration-file forms of `symlink_app_data` can enable this state even though the command-line flag is disabled for temporary app-

## Summary The pip seeder acquires bundled wheels with download=False and lets pip access the index when --download is selected. Index candidates on that path do not pass through virtualenv's wheel digest verification. Anthropic's OSS Scanner reported this as `ANT-2026-74ALJBUF` in `virtualenv-20261

## Summary Wheel downloads go directly into the reusable wheelhouse, while the verification target is selected from pip's textual output. A verification failure does not remove the downloaded file from that cache. Anthropic's OSS Scanner reported this as `ANT-2026-ST00DRO3` in `virtualenv-20261015-0

## Summary Caller-supplied prompt text can become executable syntax in the xonsh activation script. An attacker must influence the value passed to virtualenv, and a user must subsequently activate the environment. ## Affected area Xonsh reads a UTF-8 activation script using a legacy multibyte encodi

## Summary Caller-supplied prompt text can become executable syntax in the bash activation prompt. An attacker must influence the value passed to virtualenv, and a user must subsequently activate the environment and draw the prompt. ## Affected area Bash runs with compatibility level 4.2 and draws t

## Summary The venv creator reads the standard library's generated pyvenv.cfg with splitlines() and merges all resulting keys over virtualenv's configuration. Line-boundary characters from destination data can therefore become configuration structure before output sanitization. Anthropic's OSS Scann

## Summary The app-data seeder joins paths from existing distribution metadata to site-packages and deletes the resulting paths without checking containment within the environment. Anthropic's OSS Scanner reported this as `ANT-2026-SXOEHWP7` in `virtualenv-20261015-005`, received on 15 October 2026.

### Impact Origin validation error in Microsoft Authentication Library (MSAL) for Node.js allows an unauthorized attacker to disclose information over a network. This affects the auth_code flow. ### Patches Version 7.1.0 and higher are patched. ### Workarounds Ensure you pass in only the auth_code t

### Impact undici's `fetch()` crashes the Node.js process when a malicious server returns a response with more than five content codings and closes the connection before sending the body. undici rejects such responses (a content-encoding limit), but it created the internal response stream before tha

### Impact undici's `EventSource` client can be driven to exhaust process memory by a malicious or compromised Server-Sent Events peer. By sending millions of tiny completed `data:` fields with no blank event separator, or a single unfinished line split across many chunks, the parser retains a growi

### Impact undici's `fetch()` verifies Subresource Integrity (SRI) metadata by looking up the algorithm token in a lowercase-only set, but the SRI specification defines a valid token by its ASCII-lowercase form. A correct but non-lowercase token such as `SHA256-...` or `Sha256-...` is therefore trea

### Impact `serialize-javascript` escapes its output so it is safe to embed inside a ` ` element. Before 7.1.3 that guarantee did not hold for a **function value whose source ends in a bare ` `). A body ending exactly at ` ` followed by markup: ```js const serialize = require('serialize-javascript')

### Impact When `multer` is configured with an asynchronous `fileFilter`, a single request can crash the Node.js process. If a request is aborted (for example when one file is rejected) while another file's async `fileFilter` is still pending, the pending callback later resumes a parsing stream that

## Summary The ESM compiler in `[email protected]` does not validate imported local binding aliases before interpolating them into generated JavaScript. As a result, an invalid ESM import alias can be transformed into a valid JavaScript destructuring default initializer and executed. This appears to

### Summary Wasmtime may panic when the host lowers a component model `stream` or `future` into a guest, if the host created that stream or future with one payload type and the guest expects a different one. This can happen when an embedder creates a stream or future, passes it through a guest, rece

## Summary In Wasmtime prior to v43, the Cranelift compiler backend bit-packs its SSA value indices in a way that can result in silent overflow in release builds, and result in incorrect value references in the IR resulting in arbitrary miscompilation. A very large Wasm function body, or one that is

`SoftFileLock` and `MarkerSoftFileLock` evict an unparsable marker (the lock file at ` `, whose presence says a process holds the lock) once a waiting contender has watched it unchanged for two seconds. `SoftFileLease` expires a lease the same way. The watch tells two looks apart by the marker's mod

When a soft-lock stale break finds that the marker (the lock file at ` `) it renamed aside was a live one recreated by a successor, the restore branch of `break_lock_file()` checks the break name with `lstat` (a check that reads a name without following a symbolic link) and then calls `os.link(break

`ReadWriteLock` and `AsyncReadWriteLock` (the SQLite-backed reader/writer lock) hand SQLite a name they do not control. On Linux the lock validates its database through a descriptor (the number the kernel gives a process for an open file). It then connects SQLite to `/proc/self/fd/ `, a Linux path t

### Impact Fallow expands some globs from the analyzed repository on disk. Before 3.34.0, a segment such as `.*`, `.?` or `..*` in such a glob also matched the special `..` entry. The `glob` crate tests `..` against a segment that starts with a literal `.`. Fallow validates plugin glob patterns and

### Impact Fallow reads the Jest and Vitest configs of the repository that it analyzes. A Jest `projects` entry or a Vitest `test.projects` entry can name a path. Fallow followed such an entry to a config file and read that file, also when the file was outside the project root. These forms reached o

### Credits **Researcher**: Alex Bouffard ([email protected]) ### Summary A heap buffer overflow in Pillow's FlashPix (FPX) JPEG-tile decoder lets an attacker achieve arbitrary code execution by getting an application to open a single crafted file with `Image.open()`. The file is recognized by con

### Impact Decoding a header that holds a long run of joinable RFC 2047 base64 encoded words, such as `=?utf-8?B?QUJD?=` repeated tens of thousands of times in a `Subject`, `From`, `To`, a filename or a description, took time quadratic in the number of words. The join check ran a regex over the text

### Vulnerability summary RFC 5322 comments nest. addressparser ended a comment at the first `)`, including the one that closes a nested comment, and parsed the rest of the outer comment as header text. `Victim (x(y) ) ` names `[email protected]` with `x(y) ` as a comment, and Nodemailer read it as the a

### Vulnerability summary addressparser ends an RFC 5322 group at the first `;`, including one inside a quoted display name or a comment. The text after it is parsed again as top level recipients with the quoting flipped, so text that every conformant parser reads as a display name or comment become

### Vulnerability summary addressparser ends an angle-addr at the first `>` it sees, including one inside a quoted local part, a comment or a domain literal. The domain is then read off the text in front of that `>`. ` "@good.com>` is the mailbox `"[email protected]>"@good.com` under RFC 5322, and Nodemail

A vulnerability in how relationship inclusion is processed on certain read endpoints. Under specific conditions, a request to a read-only endpoint can be crafted to trigger a destructive database operation on a related table, rather than simply retrieving data. ### Impact A user with only read acces

### Impact `fast-uri` percent-decodes the scheme component with the legacy global `unescape()` before validating it, so an input whose decoded scheme is a valid but dangerous token is emitted as a live scheme. RFC 3986 section 3.1 does not allow percent-encoding in a scheme, so no RFC or WHATWG pars

### Impact `fast-uri`'s `normalize()` and `serialize()` apply RFC 3986 dot-segment removal (`remove_dot_segments`) to the path of a relative-path reference. RFC 3986 section 5.2.4 defines that algorithm only for the merged target path during resolution, not for the reference itself, so applied to th

### Impact `fast-uri` versions `>= 2.4.2, = 3.1.3, = 4.0.1, <= 4.2.2` can silently rewrite the host of an HTTP-family URL (`http`, `https`, `ws`, `wss`, or any scheme with `domainHost: true`). For those schemes `canonicalizeHost()` passes the parsed host to the WHATWG `URL` parser and adopts its `.h

### Impact `fast-uri`'s `serialize()`, `normalize()`, and `resolve()`, when called with the non-default option `reference: 'suffix'` on a reference that has no authority, emit a relative reference whose first path segment contains a bare colon without escaping it. RFC 3986 section 3.3 requires the f

## Maintainer assessment and remediation This report is accepted as a FastMCP authorization vulnerability. In supported configurations, a server transform can change the metadata used by a component's authorization policy. Direct lookups previously checked the original component but returned the tra

## Maintainer assessment and remediation This report is accepted as a FastMCP credential-binding vulnerability. Affected versions of the OAuth client credentials providers do not expose the authorization-server issuer that owns pre-registered credentials. An untrusted or compromised MCP server can t

## Summary API clients can supply arbitrary `mm_processor_kwargs` per request. vLLM forwards these values through the multimodal rendering and processing pipeline to Hugging Face and custom image/video processor constructors and calls. Resource-sensitive values such as image size, patch size, patch

### Impact Applications using enhanced form actions (`use:enhance`) on routes that accept paths beginning with `//`, such as catch-all routes, may be vulnerable to an open redirect. ### Patches A fix has been prepared for `@sveltejs/kit` 3.0.0. Users should upgrade to 3.0.0 or later. The fix preserv

### Summary `ClientIPFromXFF` skips any `X-Forwarded-For` entry in a configured trusted CIDR but never verifies that the direct TCP peer in `http.Request.RemoteAddr` belongs to that CIDR. A client that can reach the Go server directly can therefore append a trusted-looking proxy address and choose t

Pydantic AI Harness before 0.59.0 fails to enforce UsageLimits.tool_calls_limit on nested tool calls dispatched from run_code in the CodeMode toolset. Users or prompt-injected content can make the sandboxed program invoke tools via run_nested_call() without check_before_tool_call, exceeding operator

### Summary ODF style values are interpolated into `style="..."` attributes without HTML-escaping in odf-kit's ODS to-HTML renderer (`odsToHtml()`). A double-quote character inside an attacker-controlled style value breaks out of the attribute, allowing arbitrary HTML/attribute injection — and there

### Impact An attacker who uses this vulnerability can craft a PDF which leads to long runtimes. This requires loading relevant parts of a file (like their pages) where the same, but non-existent indirect object is referenced multiple times. ### Patches This has been fixed in [pypdf==6.21.2](https:/

### Impact An attacker who uses this vulnerability can craft a PDF which leads to long runtimes. This requires cross-reference streams with repeated malformed cross-reference streams. ### Patches This has been fixed in [pypdf==6.21.2](https://github.com/py-pdf/pypdf/releases/tag/6.21.2). ### Workaro

### Impact An attacker who uses this vulnerability can craft a PDF which leads to long runtimes. This requires opening a file with large/wrong upper limits in the xref table. ### Patches This has been fixed in [pypdf==6.21.2](https://github.com/py-pdf/pypdf/releases/tag/6.21.2). ### Workarounds If y

### Impact A set of eMudhra intermediate certificates were compromised and are being blocked by browsers and other TLS clients. This Electron update adds the same block to both Chromium networking and Node.js `tls`, `https` and `fetch`. On earlier versions, an attacker holding a certificate issued t

### Impact A single request can crash any application using `body-parser` with default options. When a request carries a `Content-Encoding` (for example `gzip`), `body-parser` pipes it into a decompression stream and, after reading the body, leaves that stream piped with no error listener. A payload

mem0 0.1.117 before 1.0.8 contains an sql injection vulnerability in mem0/vector_stores/databricks.py that allows attackers to inject SQL by influencing stored memory content. Attackers can supply crafted memory text, metadata, or message names that reach unescaped insert() and update() string inter

## Summary In the `gix` crate, `Cache::protect_options()` in `gix/src/config/cache/access.rs` reads the three filesystem path-protection settings (`core.protectHFS`, `core.protectNTFS`, and `gitoxide.core.protectWindows`) with the unfiltered `gix_config::File::boolean()` accessor instead of the trus

### Impact Three issues allowed actions protected by the `#[Authorize]` attribute to run against records the current user is not authorized for: 1. **Out-of-order parameter keys on actions.** `#[Authorize]` resolved a model parameter by its array key, while the action itself received parameters posi

## Impact In Echo v5, `ExtractIPFromRealIPHeader` checked whether the address supplied in `X-Real-IP` belonged to a trusted range instead of checking the address of the direct network peer. An untrusted client could therefore supply a loopback or private address and have it returned by `c.RealIP()`

## Impact Echo's Proxy middleware could retain a handler, copy goroutines and network connections after a WebSocket client disconnected if the upstream kept its connection open. The raw proxy waited for both copy directions to finish without reliably closing the other connection when one direction e

## Impact Echo v4's opt-in Decompress middleware exposed a gzip-decoded request stream without limiting its expanded size. A small compressed request could therefore produce a very large decoded body. Handlers that read or bind that body could consume excessive memory or CPU, and repeated or concurr

## Impact Echo's Proxy middleware selected a raw tunnel when the client requested a WebSocket upgrade, before validating whether the configured upstream accepted it. If the upstream returned an ordinary HTTP response and kept the connection alive, subsequent HTTP requests on that connection were for

## Impact Echo v5's BodyDump middleware captured a bounded prefix, drained the remaining request body while ignoring read errors, and then replaced the body with the captured prefix. With an outer BodyLimit, an unknown-length request such as an HTTP/1.1 chunked request, and a BodyDump capture limit

## Impact Echo v4's opt-in BodyDump middleware read complete request bodies into memory and retained complete response bodies without a capture limit. A client able to submit large requests to a route using BodyDump could cause large allocations before the application handler ran. Large responses, i

**Summary** Strands Agents SDK is an open-source SDK, available for Python (strands-agents) and TypeScript (@strands-agents/sdk), for building and running AI agents. An issue exists where, under certain circumstances, the Agent2Agent (A2A) server shares conversation history across callers with diffe

## Summary The bash activator puts the caller-supplied prompt value into `PS1` unescaped whenever `promptvars` is off at activation time, and assumes prompt expansion can never run afterwards. `promptvars` and posix mode are runtime shell state, not a property of the activation moment: re-enabling p

The Include directive in `src/mistune/directives/include.py` does not validate that the resolved file path stays within the source directory, allowing path traversal via `../` sequences to read arbitrary files. Additionally, error messages and included file contents are rendered without HTML escapin

## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-h7ww-273w-6cm8. This link is maintained to preserve external references. ## Original Description Mistune before 3.3.0 contains a path traversal vulnerability in the Include directive that allows attackers to rea

## Summary An infinite-loop vulnerability (CWE-835) in the Twisted IMAP4 server lets an authenticated client freeze the whole process with one small command. `twisted.mail.imap4.parseNestedParens` reads an IMAP literal size with `int()` and never rejects a negative value. A negative size such as `{-

## Summary An unbounded-buffer vulnerability (CWE-770) in the Twisted words IRC server lets any unauthenticated remote client exhaust server memory. `twisted.words.protocols.irc.IRC.dataReceived` appends every received byte to a per-connection buffer and only removes data at a line feed, with no max

## Summary An allocation-without-limits vulnerability (CWE-770) in the Twisted conch telnet transport lets any unauthenticated remote peer exhaust server memory over a single connection. When the peer opens a telnet subnegotiation with `IAC SB` and then streams bytes without ever sending the `IAC SE

## Summary An allocation-without-limits vulnerability in the Twisted XML element stream lets any unauthenticated remote peer exhaust server memory over a single stream. When the peer opens a container element and streams child elements without ever closing the container, every element is materialise

## Summary Multimodal content parts (`image_url`, `video_url`, `input_audio`, ...) accept a user-supplied `uuid` field that vLLM uses **verbatim as the item's cache identity** (`mm_hash`). The two frontend/engine processor caches (P0 "sender" cache in the API process, P1 "receiver" cache in the Engi

### Impact Applications that prerender pages and use `setHeaders` to set a `cache-control` header from an untrusted source are vulnerable to cross-site scripting (XSS). SvelteKit inserts the header value into a ` ` tag without escaping it. An attacker who can influence this value at prerender time c

A buffer overflow vulnerability in the Brotli decoder (c/dec/decode.c) in Google Brotli versions 1.0.3 through 1.2.0 on all platforms allows a remote unauthenticated attacker to corrupt adjacent decoder state memory, disclose sensitive memory contents, cause a denial of service, or potentially execu

### Summary `create_entity`, `link_entities`, `rename_entity`, `unlink_entities` and `delete_entity` regenerate a memory note's body from SQLite at the computed `memory/ / .md` path. When a note already existed at that path and was not owned by the entity being written (a hand-authored note, or an o

## Summary `installBazaarPlugin` (and the equivalent endpoints for widgets/icons/templates/themes) accept `packageName`, `repoURL`, and `repoHash` as independent request fields with no validation that they refer to the same package. `packageName` alone determines the install destination; `repoURL`/`

### Summary Two checks on the same WebSocket request URI parse it differently. The authentication exemption for keepalive sessions matches raw substrings, while the quarantine introduced to contain those sessions reads a parsed query parameter. Because Go's `url.Values.Get` returns only the first va

### Summary `/api/filetree/authFilePublishAccess` is registered with `CheckAuth` only and is reachable anonymously. It never sets a failure code, so its outcome is signalled entirely by the response message and by whether a `Set-Cookie` header is present. Those two signals differ across access tiers

### Summary `/api/av/getAttributeViewBacklinks` filters its results for reader roles through `FilterAttributeViewBacklinksByPublishAccess`. That function resolves its ignore list with `GetDisablePublishAccess`, which covers only the forbidden tier. Documents at the hidden tier are absent from that l

### Relationship to GHSA-hgfg-j9pg-43xw That advisory concerned the administrator's live UI layout, and commit `63c7d5474` resolved it by removing `FilterUILayoutByPublishIgnore` and nulling `Conf.UILayout` for readers. That fix is correct and complete for the live layout. This report concerns a dif

### Impact The Streamable HTTP transport was constructed without `enableDnsRebindingProtection`/`allowedHosts`/`allowedOrigins` and performed no `Origin`-header validation. With the documented `auth.mode: "none"` loopback default, a **drive-by web page could `POST http://127.0.0.1/mcp`** and receive

### Impact Bridge tool results filtered only the `items` array against the read ACL and passed sibling fields through unfiltered: `tasks_filter` emitted `groups` whose counts reflected denied notes, `makemd_query` returned `...result` siblings, and `list_templates` enumerated Templater template path

### Summary On a Streamable HTTP deployment with `auth.jwtSecret` configured, serving a 2026-07-28-era client that declared `elicitation.form` support, a call to a dispatch-gated tool (`destructive: true`, or a scope with an HITL floor) that was offered an `inputRequired` confirmation could still co
