## Affected packages

- `wwbn/avideo` (Packagist): affected `<=29.0`; no fixed version yet

## Machine-written summary

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

> Wwbn AVideo (Packagist wwbn/avideo) versions up to and including 29.0 have a cross-site request forgery flaw in the configuration update endpoint, which lets a page on another site change the site's global settings. An attacker needs to get a logged-in administrator to visit a malicious page; the request then rewrites settings such as the encoder URL and SMTP credentials, which can lead to stored script injection and credential exposure. No fixed version is listed. The source suggests adding a CSRF check to the endpoint, but no official fix or workaround is given.

## 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-vvfw-4m39-fjqf>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
