## Affected packages

- `bref/bref` (Packagist): affected `<2.1.13`; fixed in `2.1.13`

## Machine-written summary

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

> GHSA-82vx-mm6r-gg8w affects the bref/bref Composer package for versions before 2.1.13 when used with the Event-Driven Function runtime and a RequestHandlerInterface handler. Multipart request parts whose keys end with an open square bracket are parsed differently than in plain PHP, which may lead to application-dependent vulnerabilities or undefined behavior. The source suggests using PHP's parse_str to mimic plain PHP behavior, and the fix is in 2.1.13, so upgrading to 2.1.13 or later is the remedy.

## 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-82vx-mm6r-gg8w>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
