CVE-2023-48909Public exploitNetwork attack vector

Disputed code execution via exposed FFmpeg arguments

Published Jan 12, 2024 · Updated Jun 6, 2025

Alleged command execution in JAVE2 3.3.1 allows attackers to run arbitrary code when an application exposes FFmpeg arguments. The published proof passes attacker-controlled values to ProcessWrapper.addArgument, which deliberately forwards them as FFmpeg arguments rather than invoking a shell. The upstream project disputes that this is a JAVE2 defect because paths are made absolute and Runtime.exec receives an argument array; code execution requires a calling application to expose FFmpeg instruction control.
