## Machine-written summary

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

> Magick.NET packages (Q16 variants, including AnyCPU, HDRI, OpenMP and architecture-specific builds) before version 14.10.1 are affected. ImageMagick fails to detect circular references between two MVG files, which causes a stack overflow when such a file is read. An attacker who can supply an MVG file for processing can cause a denial of service. Upgrade to version 14.10.1 or later. The source gives few details about the exact trigger.

## 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-7rvh-xqp3-pr8j>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
