## Summary The builtin creator accepts existing directory symlinks through ensure_dir() and writes environment files through those directories. This permits writes outside the requested destination. Anthropic's OSS Scanner reported this as `ANT-2026-MUFJEG11` in `virtualenv-20261015-005`, received o

## Summary The deletion error handler obtains permission bits with lstat() but applies them through chmod(), which follows symlinks. On an eligible unlink failure this can change permissions outside the destination. Anthropic's OSS Scanner reported this as `ANT-2026-UK90QC27` in `virtualenv-20261015

## Summary A destination path supplied to virtualenv can be interpreted as shell syntax by a generated POSIX console launcher. The app-data seeder and pip delegate launcher generation to distlib but supply the interpreter path in a form that does not preserve it as literal data in the shell wrapper.

### Summary The MSP RLE decoder expands run-length data into an in-memory buffer with no cap tied to the declared image size. A small file that passes the pixel-count check can force hundreds of megabytes or more of allocation when the application loads pixels. ### Details The MSP decoder writes eac

### Summary `PdfParser`'s `get_value()` can recurse without any limit and crash with an uncaught `RecursionError`. It is reachable through `Image.save(im, fp= , format="PDF", append=True)` when the existing PDF file is attacker-controlled. This is the same class of bug as https://github.com/advisori

### Summary On `main`, even with the guard in #9725, it's possible to have these decoders read 1 to 3 bytes past the end of the passed buffer with a suitable width/height. ### Details `ImagingRawDecode` and the `P;2L` / `P;4L` unpackers disagree about how many bytes a line of data occupies. The raw

### Summary `PIL.EpsImagePlugin.Ghostscript()` builds the Ghostscript command line using the input file path (`fp.name`) **without sanitization**, placing it at `-f `. A filename beginning with `-` is interpreted by Ghostscript as an option, giving command-line argument injection; chainable to RCE (

### Impact An attacker who uses this vulnerability can craft a PDF which leads to arbitrary image parsers being called. This requires loading an image which claims to use the `/DCTDecode` filter (JPEG data). Users which do not have the optional *Pillow* dependency installed in their environment are

### Summary In Vitest 5, Vite's `server.fs.deny` is not applied as intended on Vitest's dev servers. Depending on the server, files that Vite refuses to serve by default (such as `.env`, private keys and certificates, `.npmrc`, and `.git`) or Vitest's own API token file (`.vitest-secret-token`) can

### Summary `@vitest/mocker`'s `interceptorPlugin` accepts mock registrations on Vite's dev-server WebSocket with no authentication, and interpolates the mock's `url` into generated module source without escaping. A client that can reach the dev server can make it serve arbitrary JavaScript in place

## Summary The path traversal fix released for [GHSA-82fw-gwwq-j7x9](https://github.com/vitest-dev/vitest/security/advisories/GHSA-82fw-gwwq-j7x9) can be bypassed on Windows by using a backslash in the redirect URL pathname. The fixed code joins an attacker-controlled URL pathname with the Vite root

## Summary When a user exports content through `@apostrophecms/import-export`, the module copies the generated archive into uploadfs at `/exports/` and returns a public URL under `/uploads/exports/`. The filename is fully deterministic: site `shortName`, document type, a `YYYYMMDDHHmmss` timestamp,

### Summary Browser CDP discovery could accept blocked WebSocket URLs. In affected versions, a lower-trust caller or configured input path could reach network destinations that should have been blocked by OpenClaw policy. This advisory is scoped to the named feature and configuration. It does not ch

**Summary:** A malicious website may be able to cause unauthorized file changes in a developer’s project while an affected Storybook development server is running. Under additional conditions, a changed file could be executed by a local runtime with the developer’s privileges. We are not aware of ex

## Summary ApostropheCMS widget styles support project-defined schema fields. If a project defines a free-form `string` style field with a CSS `property` and no selector, an editor-controlled value is rendered as an inline CSS declaration. The resulting declaration is then inserted into the widget w

#### 1. Summary The API endpoint `POST /api/v1/@apostrophecms/import-export/clean-export` in `@apostrophecms/import-export` lacks authentication and authorization checks. Any client—including unauthenticated anonymous users who have obtained the standard CSRF cookie from visiting the site—can direct

### Summary ApostropheCMS lets a module expose an anonymous read API by setting `publicApiProjection`, which whitelists the document fields unauthenticated callers may see. The public REST GET handler applies every launderable query builder from the query string *before* forcing that projection. Two

### Summary The color field accepts any string that *begins* with a valid `rgb()` / `hsl()` color, because `TinyColor.isValid` does not anchor its match at the end of the string. An authenticated user with edit rights can store arbitrary HTML after a valid color prefix. When the stored value is rend

### Summary Since 2.18.0, when an ` ` is not allowed and `disallowedTagsMode` is `'discard'` (the defaults), its raw-text content is re-sanitized by a recursive call to `sanitizeHtml(text, options)` (the change from #5564, fixing #5550). The recursion has no bound and starts each nested call with a

### Impact An attacker who uses this vulnerability can craft a PDF which leads to an infinite loop. This requires calling `find_outline_item` on a `PdfWriter`. ### Patches This has been fixed in [pypdf==6.20.1](https://github.com/py-pdf/pypdf/releases/tag/6.20.1). ### Workarounds If you cannot upgra

### Impact An attacker who uses this vulnerability can craft a PDF which leads to an infinite loop.

### Summary The bash `activate` script escapes the environment name for only one of the two passes bash makes over `PS1`, so a backslash in the name undoes the escaping and a name containing `\$(...)` runs as commands in the user's shell each time bash draws the prompt. ### Affected area `src/virtua

### Impact An attacker who uses this vulnerability can craft a PDF which leads to large memory consumption. This requires accessing any stream with a large amount of filters or multiple filters which pass around large amounts of data. ### Patches This has been fixed in [pypdf==6.20.0](https://github

### Summary When accessing a malicious site while a dev server using Vite is running, that site was able to load scripts in a page served by the dev server. ### Impact Only apps that match the following conditions are affected: - the dev server passes an unchanged browser request URL to `server.tran

### Impact zsh users activate an environment with the bash `activate` script, which puts the environment name into `PS1`. Since 21.13.0 the script escapes backslashes, dollar signs and backticks in that name, but only when `BASH_VERSION` is set, so zsh gets the raw value. With the `PROMPT_SUBST` opt

### Impact `FishActivator` defines no `quote()`, so it inherits `ViaTemplateActivator.quote`, which returns `shlex.quote(string)`. That function follows POSIX `sh` rules, where a backslash inside single quotes stays a literal character. fish reads `\'` inside single quotes as an escaped quote and `\

### Impact `ViaTemplateActivator.instantiate_template` replaces the placeholders in an activation template one key at a time, each across the whole text. When a value that it already substituted and quoted contains the name of a later placeholder, the later pass rewrites that name inside the quoted

### Summary Slack Morphism exposes the correct Slack request HMAC when signature verification fails. For an invalid request, `slack-morphism` computes the correct signature for the attacker-controlled timestamp and request body and stores it in `SlackEventWrongSignatureError.generated_hash`. The err

### Summary OGNL's optional *stricter invocation* mode maintains a block list that prevents expressions from directly calling methods on dangerous classes such as `Runtime`, `ProcessBuilder`, and `ClassLoader`. The block list filters on the **declaring class of the method OGNL invokes**. Because `ja

## Summary The OpenChoreo API server authorized `PUT .../workflowruns/{runName}` against ownership metadata taken from the request body, while the object it actually mutated was selected by the URL path. Nothing forced the two to agree. A `WorkflowRun`'s membership in a project and component is carr

Exclusive XML canonicalization (`http://www.w3.org/2001/10/xml-exc-c14n#`) in `github.com/moov-io/signedxml` copied the entire accumulated namespace map at every node during `ValidateReferences()`, before any reference digest or signature check. For a chain of nested elements that each declare many

## Summary A potential unauthenticated denial-of-service vulnerability exists in the chunked import upload path used by `@apostrophecms/import-export`. The affected import API routes invoke: `self.apos.http.bigUploadMiddleware()` before the actual import handler performs its authentication check. Be

### Summary A stored Cross-Site Scripting (XSS) vulnerability exists in the incident creation form, allowing an authenticated attacker to inject malicious HTML/JavaScript that executes in the browser of any user who views the status page, potentially leading to session token theft and account takeov

### *Impact.** Push notification bearer tokens and authentication credentials submitted by clients are written to server log files in cleartext. Any operator, log aggregation system, or attacker with log access can read these secrets and use them to authenticate to the client's push notification end

## Summary A small attacker-supplied TIFF can be opened and loaded normally, then reach an out-of-bounds read when an application saves it back to TIFF with retained metadata. The fixed reproducer is a 1×1, 16-bit grayscale, PackBits-compressed TIFF containing tag 320 (ColorMap) with **768 SHORT val

### Summary When an application appends to an existing PDF with `Image.save(..., format="PDF", append=True)`, Pillow parses that file with `PdfParser`. Two recursive parsers have no effective bound. `linearize_page_tree` follows `/Kids` with no visited set or depth limit, so a cyclic or duplicated p

## Summary `JpegImageFile.draft()` — which `Image.thumbnail()` calls automatically — requests 1/2, 1/4 or 1/8 scaled JPEG output and shrinks `self._size` and the tile extents to match, so `_setimage()` allocates a single-row decode buffer of `ceil(W/s)` samples. `ImagingJpegDecode()` sets `cinfo.sca

An incomplete fix for [GHSA-58c5-g7wp-6w37](https://github.com/angular/angular/security/advisories/GHSA-58c5-g7wp-6w37) (`CVE-2025-66035`) in `@angular/common`'s HTTP Client (`HttpClient`) allows Cross-Site Request Forgery (XSRF) tokens to be leaked to attacker-controlled cross-origin domains when r

### Summary A link reference definition whose label or title is never closed is O(n²) in markdown-it 15.0.2 with default options. Continuation lines are pulled lazily with str += lineContent in src/rules_block/reference.ts, and the subsequent charCodeAt and slice calls flatten the V8 cons-string, co

### Summary With `html: true`, markdown-it takes quadratic time to parse repeated unterminated HTML constructs inside a paragraph. This affects HTML comments (` `, `?>`, `>`, and `]]>`. When the terminator is absent, matching fails. Parsing eventually reaches the next opener and scans an overlapping

### Summary In affected versions, servers put no limit on how many array elements and object keys they validated in one request. One HTTP request within the default 4 MiB size limit could exhaust the server's memory, and the process aborted with `JavaScript heap out of memory`. No credentials are ne

### Summary In affected versions, the SDK's server-side bearer authentication had no way to check that a token was issued for your server (its audience). Where one authorization server issues tokens for several services, a valid token for another service was also accepted by your MCP server. ### Am

### Impact Even though it is correctly applied to guests, contributors, etc., `viewRole` is not applied to the general public. This means that a secured content type like `@apostrophecms/user` can in theory be accessed. This is greatly mitigated by the fact that there is no automatic public REST API

## Summary The notification module exposes `PATCH` and `DELETE` REST endpoints that perform operations directly on the underlying MongoDB collection without verifying that the requester is authenticated or owns the target notification. As a result, an unauthenticated attacker who obtains a valid not

### Summary The tar-extraction guard added to `@apostrophecms/import-export` for GHSA-mwxc-m426-3f78 is a literal substring test for `../`, and `./..` does not contain that substring. An entry named `./..` therefore passes the guard, `path.join` normalizes it to the parent of the export directory, a

## Summary The `uploadfs` library's local storage backend does not validate or sanitize user-supplied paths. The `prefixPath()` helper only strips double slashes (`//`) and the backend performs direct string concatenation (`uploadsPath + path`). An attacker can inject `../` sequences to escape the i

## Summary sanitize-html 2.17.7 introduced `animatesUrlAttribute()` to block SVG animation elements (`animate`, `animateColor`, `animateMotion`, `animateTransform`, `set`) when their `attributeName` targets a URL sink like `href`. However, this check is bypassed when the animation element uses a nam

**Summary** ApostropheCMS’s exist-in-locale API allows an authenticated low-privilege user to determine whether restricted documents exist in a specified locale and mode, including draft mode. The endpoint returns localized document identifiers without applying document-level view or edit authorizat

## Summary `@apostrophecms/import-export`'s update-by-key feature lets an imported document carry a ` :key` property (for example `slug:key`) whose value is used to find an existing document to update instead of inserting a new one. `getUpdateKey()`/`insertOrUpdateDocWithKey()` (`lib/methods/import.

## Summary The client-side helper `apos.http.parseQuery()` in ApostropheCMS builds a nested object from a URL query string without sanitizing the keys `__proto__`, `constructor`, or `prototype`. Parsing an attacker-controlled query string therefore writes arbitrary properties onto `Object.prototype`
