This issue affects some unknown processing of the file clones.json.php. Such manipulation leads to os command injection. This vulnerability is uniquely identified as CVE-2026-33478. The attack can be launched remotely. No exploit exists. It is advisable to implement a patch to correct this issue. Detailsinfo A vulnerability, which was classified as critical, has been found in WWBN AVideo up to 26.0. Affected by this issue is an unknown code block of the file clones.json.php. The manipulation with an unknown input leads to a os command injection vulnerability. Using CWE to declare the problem leads to CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. Impacted is confidentiality, integrity, and availability. CVE summarizes: WWBN AVideo is an open source video platform. In versions up to and including 26.0, multiple vulnerabilities in AVideo's CloneSite plugin chain together to allow a completely unauthenticated attacker to achieve remote code execution. The `clones.json.php` endpoint exposes clone secret keys without authentication, which can be used to trigger a full database dump via `cloneServer.json.php`. The dump contains admin password hashes stored as MD5, which are trivially crackable. With admin access, the attacker exploits an OS command injection in the rsync command construction in `cloneClient.json.php` to execute arbitrary system commands. Commit c85d076375fab095a14170df7ddb27058134d38c contains a patch. The advisory is shared for download at github.com. This vulnerability is handled as CVE-2026-33478 since 03/20/2026. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. There are known technical details, but no exploit is available. The MITRE ATT&CK project declares the attack technique as T1202. By approaching the search of inurl:clones.json.php it is possible to find vulnerable targets with Google Hacking. Applying the patch c85d076375fab095a14170df7ddb27058134d38c is able to eliminate this problem.
