CVE-2026-92912 Details
Description
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.
A vulnerability exists in AVideo versions through c3edcc274c389816d434acadac07ee78eaf330c1, where RTMP publish keys for live transmissions are generated using cryptographically weak uniqid() values. This method reduces the key's entropy to approximately one million possibilities per second. Attackers aware of the channel's creation time can brute-force the microsecond component of the key to forge valid stream keys, enabling them to broadcast content as if they were the channel owner.
No official patch is available. However, it is suggested to replace the uniqid() function with a more secure alternative, such as bin2hex(random_bytes(16)).
