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.
