## Machine-written summary

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

> Sentry versions up to and including 8.2.0 are vulnerable to remote code execution. An attacker who is an authenticated superuser can inject malicious pickle-serialized data through the audit log entry data parameter, which lets them run arbitrary commands with application privileges. No fixed version is listed in the source, and it gives no workaround.

## 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-444r-2whx-3685>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
