## 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.

> The CloneSite plugin in wwbn/avideo, versions up to and including 29.0, passes a user-supplied URL into a shell command without adequate sanitization. An attacker with administrator access who can supply a crafted URL can inject shell commands and run arbitrary code on the server. No fixed version is listed, and the source gives no workaround beyond sanitizing the URL input.

## 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-xr6f-h4x7-r6qp>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
