What is CVE-2026-82644?

WWBN AVideo versions e01e41ecc and earlier are susceptible to a vulnerability that allows attackers to bypass rate limiting on login attempts. The issue lies in the enforceRateLimit() function, which utilizes a cache layer to track login attempts. This mechanism erroneously classifies clients without a User-Agent header as bots and fails to increment the attempt counter for those requests. Consequently, an unauthenticated attacker can exploit this oversight by submitting an unlimited number of login attempts, potentially leading to successful unauthorized access through password-guessing tactics.
