Published by the GitHub Advisory Database at 21 Jan 2022, 23:39 UTC. agentprime has not analysed this yet, so whether it affects any app is not known.

## Affected packages

- `de.tum.in.ase:artemis-java-test-sandbox` (Maven): affected `<1.7.6`; fixed in `1.7.6`

## Machine-written summary

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

> GHSA-883x-6fch-6wjx concerns the Maven package de.tum.in.ase:artemis-java-test-sandbox (also known as Ares) in versions before 1.7.6. A malicious test submission can craft a subclass of InvocationTargetException that bypasses the exception sanitization applied during test failure processing, letting student code run in a trusted context. The attacker could then disable the security manager and gain full control of the system. Update to version 1.7.6 or later. As a workaround, forbid student classes in trusted packages.

## 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-883x-6fch-6wjx>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
