## Affected packages

- `moodle/moodle` (Packagist): affected `>=2.7.0, <2.7.3 || >=2.6.0, <2.6.6 || >=2.5.0, <2.5.9`; fixed in `2.7.3`, `2.6.6`, `2.5.9`

## Machine-written summary

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

> Moodle versions 2.5.0 to before 2.5.9, 2.6.0 to before 2.6.6, and 2.7.0 to before 2.7.3 are affected. The password generator produces too few possible temporary passwords, so a remote attacker can brute-force a temporary password and gain access to an account. Upgrade to Moodle 2.5.9, 2.6.6, 2.7.3 or later. The source does not list a 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-9v64-447r-wch6>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
