## Machine-written summary

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

> Apache Tomcat versions 11.0.0, 10.1.31 and 9.0.96 are affected. A change to pooled JSP tags can stop some tag output from being escaped, which could allow cross-site scripting, and the source gives few details on what an attacker needs. Upgrade to Apache Tomcat 11.0.1, 10.1.33 or 9.0.97 or later, matching your major version.

## 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-f632-9449-3j4w>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
