> BuildKit (github.com/moby/buildkit) versions before 0.12.5 are vulnerable. A malicious BuildKit client or frontend can send a crafted request that crashes the BuildKit daemon with a panic. Upgrade to version 0.12.5 or later; as a workaround, avoid using frontends from untrusted sources.

## 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-9p26-698r-w4hx>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
