Published by the GitHub Advisory Database at 6 Aug 2026, 21:09 UTC. agentprime has not analysed this yet, so whether it affects any app is not known.

## Affected packages

- `org.jsoup:jsoup` (Maven): affected `>=1.14.3, <1.23.1`; fixed in `1.23.1`

## Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

> The jsoup package (Maven org.jsoup:jsoup) versions 1.14.3 up to 1.23.1 are affected. When a custom Safelist permits raw-text elements, malformed HTML with a tag name ending in a control character may be sanitized incorrectly, so content meant to stay as text can be emitted as active markup, potentially enabling cross-site scripting. Upgrade to jsoup 1.23.1. Until then, do not permit raw-text elements in custom Safelists used to clean untrusted HTML.

## Check whether this affects you

A Match means an installed version is in the affected range above. Most don’t affect the app; agentprime hasn’t analysed this one yet.

- With the agentprime MCP server (<https://api.agentprime.io/mcp>), ask your agent to check the project: `check_lockfile` sends a lockfile, `check_packages` a list of installed packages, and both return the Matches and the upgrades that clear them. `get_advisory` returns this record. Setup: <https://agentprime.io/mcp.md>
- In a browser: <https://agentprime.io/check/> reads your lockfile in the browser, never uploading it.
- Whether it touches your code, with file and line: the Claude Code plugin, <https://agentprime.io/plugin.md>
- As JSON: <https://api.agentprime.io/v1/advisories/GHSA-pmhh-3w7g-xqp8>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
