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."}],"source":{"advisory":"GHSA-687q-32c6-8x68","discovery":"UNKNOWN"}},"adp":[{"references":[{"url":"https://github.com/WWBN/AVideo/security/advisories/GHSA-687q-32c6-8x68","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-03-23T21:36:16.759404Z","id":"CVE-2026-33478","options":[{"Exploitation":"poc"},{"Automatable":"yes"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-03-23T21:40:58.174Z"}}]}}
