{"id":"CVE-2026-33478","summary":"AVideo Multi-Chain Attack: Unauthenticated Remote Code Execution via Clone Key Disclosure, Database Dump, and Command Injection","details":"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.","aliases":["GHSA-687q-32c6-8x68"],"modified":"2026-08-12T03:51:34.021698608Z","published":"2026-03-23T14:01:19.611Z","database_specific":{"cwe_ids":["CWE-284","CWE-78"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33478.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33478.json"},{"type":"ADVISORY","url":"https://github.com/WWBN/AVideo/security/advisories/GHSA-687q-32c6-8x68"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33478"},{"type":"FIX","url":"https://github.com/WWBN/AVideo/commit/c85d076375fab095a14170df7ddb27058134d38c"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/wwbn/avideo","events":[{"introduced":"0"},{"fixed":"c85d076375fab095a14170df7ddb27058134d38c"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"26.0"}],"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:wwbn:avideo:*:*:*:*:*:*:*:*"}}],"versions":["26.0","25.0","24.0","22.0","21.0","18.0","14.3.1","14.3","12.4","11.6","11.5","11.1.1","11.1","11","10.8","8.9.1","8.9","8.7","8.6","8.5","8.1","7.8","7.7","7.6","7.4","7.3","7.2","4.0","3.4","2.7","2.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-33478.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H"}]}
