Vulnerability in Wwbn Avideo
CVE-2026-92912
AVideo through c3edcc274c389816d434acadac07ee78eaf330c1 uses cryptographically weak uniqid() values for RTMP publish keys in LiveTransmition, reducing key entropy to approximately one million possibilities per creation second. Attackers who know the channel creation time can brute-force the five-digit microsecond component to forge valid stream keys and broadcast content as the channel owner.
