AI-suggested
Organizations should immediately apply the patch referenced in commit c85d076375fab095a14170df7ddb27058134d38c or upgrade to a version beyond 26.0 where this vulnerability is fixed. Until patched, restrict network access to the affected endpoints (`clones.json.php`, `cloneServer.json.php`, and `cloneClient.json.php`) using firewalls or web application firewalls (WAFs) to limit exposure. Implement strict access controls and monitor logs for unusual activity related to these endpoints. Replace MD5 password hashes with a strong, modern hashing algorithm (e.g., bcrypt, Argon2) to prevent trivial cracking if database dumps occur. Conduct regular security audits of plugins and third-party components. Employ intrusion detection systems to detect command injection attempts and anomalous rsync usage. Finally, educate administrators on the risks of using outdated software and the importance of timely patching.
Description
CVE-2026-33478 is a critical remote code execution vulnerability in WWBN AVideo versions up to 26.0. It involves a chain of flaws in the CloneSite plugin that allows unauthenticated attackers to access secret keys, dump the database including weakly hashed admin passwords, and ultimately execute arbitrary OS commands via an injection in the rsync command. The vulnerability requires no authentication or user interaction and affects confidentiality, integrity, and availability severely. A patch is available in commit c85d076375fab095a14170df7ddb27058134d38c. Organizations using AVideo should urgently update to a fixed version to prevent exploitation. The CVSS score is 10.0, reflecting the critical nature of this flaw.
