CVE-2024-51366Public exploit

Arbitrary code execution via unsafe XML deserialization

Published Nov 21, 2024 · Updated Jul 5, 2026

Arbitrary code execution in OmegaT 6.0.1 allows attackers to run code when a crafted segmentation.conf file is loaded. The SRX class passes the user-writable segmentation.conf file to Java XMLDecoder, which instantiates attacker-specified objects and invokes their methods during startup. Exploitation requires placing the file in the user's OmegaT configuration directory; the public proof of concept launches a process with that user's privileges when OmegaT starts.
