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.","published_at":"2026-03-23T14:01:19.611000Z","last_modified_at":null,"cvss_v3_score":10.0,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","cvss_v3_severity":"CRITICAL","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-78","CWE-284"],"nvd_references":["https://github.com/WWBN/AVideo/security/advisories/GHSA-687q-32c6-8x68","https://github.com/WWBN/AVideo/commit/c85d076375fab095a14170df7ddb27058134d38c"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:29:54.588886Z"},"effective_severity":"CRITICAL","badges":["poc"],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"C","value_label":"Changed"},{"metric":"C","name":"Confidentiality","value":"H","value_label":"High"},{"metric":"I","name":"Integrity","value":"H","value_label":"High"},{"metric":"A","name":"Availability","value":"H","value_label":"High"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"wwbn","vendor_name":"WWBN","product_slug":"avideo","product_name":"AVideo","version_start":"<= 26.0","version_start_inclusive":true,"version_end":"<= 26.0","version_end_inclusive":true,"cpe23_uri":"cve5:wwbn:avideo:<= 26.0:<= 26.0"}],"exploit_refs":[{"source":"nuclei","kind":"nuclei","url":"https://github.com/projectdiscovery/nuclei-templates/blob/main/http/cves/2026/CVE-2026-33478.yaml","title":"AVideo <= 26.0 - WWBN AVideo - Remote Code Execution","author":"pussycat0x","disclosed_at":null}],"news":[],"references":[{"url":"https://github.com/WWBN/AVideo/security/advisories/GHSA-687q-32c6-8x68","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/WWBN/AVideo/commit/c85d076375fab095a14170df7ddb27058134d38c","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-03-23T14:01:19.611000Z","label":"CVE published","source":null},{"type":"poc_available","at":"2026-06-24T00:29:48.638073Z","label":"Public PoC available","source":"nuclei"},{"type":"cvss_changed","at":"2026-06-28T17:53:15.351162Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:53:15.351162Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:53:15.351162Z","label":"CVSS score revised","source":"cvelistv5"}]}
