A division by zero vulnerability was discovered in FFmpeg using a fuzzer built with a 'vibecoded' approach, likely meaning AI-assisted or rapid prototyping. The bug was found through automated testing, highlighting the effectiveness of such methods in uncovering edge cases in complex media processing software. The discovery underscores the ongoing need for robust fuzzing in open-source projects, and the role of novel tooling in improving security.

The exact details of the vulnerability are not yet public, but the find demonstrates practical value in combining modern development practices with security research.
