CVE-2023-30844Network attack vector

Terminal corruption via unescaped remote control characters

Published May 8, 2023 · Updated Jan 29, 2025

Output neutralization failure in Mutagen before 0.16.6 and 0.17.0 through 0.17.0 allows remote authenticated users to corrupt terminals. The list and monitor commands and daemon logging render control characters from endpoint errors, paths, names, and logs without neutralization; Mutagen Compose is affected before 0.17.1. An attacker must control a synchronized file or remote synchronization or forwarding endpoint and induce operator viewing; ordinary modern terminals face display corruption, while code execution is limited to susceptible legacy terminals.
