## Affected packages

- `sharp` (npm): affected `<0.35.5`; fixed in `0.35.5`

## Machine-written summary

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

> The sharp npm package versions below 0.35.5 are affected by a memory-related vulnerability in its bundled librsvg dependency, which the source says can lead to remote code execution on glibc-based Linux under certain runtime conditions. The source does not describe what an attacker must do beforehand, such as supplying a crafted SVG image, though sharp's decoding of SVG images is the relevant path. Upgrade sharp to 0.35.5 or later, which provides librsvg 2.63.2; users with a globally installed librsvg should move to librsvg 2.63.2.

## 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-wq5f-xc86-pv6w>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
