CVE-2026-84483: Use of Hard-coded Cryptographic Key in WWBN AVideo
WWBN AVideo through commit 9c39d8c8 contains an incomplete authentication bypass in encryptPass.json.php that allows unauthenticated attackers to compute valid HMAC tokens using the public site URL and current time. Attackers can forge authentication tokens by computing hash_hmac with the site's base URL as the key and submit arbitrary passwords to receive encrypted hashes, enabling offline precomputation attacks against stolen password databases.
