## Affected packages

- `moodle/moodle` (Packagist): affected `>=3.7.0, <3.7.3 || >=3.6.0, <3.6.7 || >=3.5.0, <3.5.9`; fixed in `3.7.3`, `3.6.7`, `3.5.9`

## Machine-written summary

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

> Moodle versions 3.5.0 before 3.5.9, 3.6.0 before 3.6.7, and 3.7.0 before 3.7.3 do not revoke role capabilities correctly. When a cohort role assignment was removed, the associated capabilities were not always revoked, so a user could keep permissions they should have lost. The source gives few details on who can exploit this or how. Upgrade to Moodle 3.5.9, 3.6.7, 3.7.3, or later.

## 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-g9m2-c2x5-fr2v>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
