{"id":"CVE-2026-45578","summary":"WWBN AVideo Live: OS command injection in on_publish.php execAsync via unescaped m3u8 URL","details":"WWBN AVideo is an open source video platform. In 29.0 and earlier, there is a classic shell-metacharacter injection. The YPTSocket notification branch in plugin/Live/on_publish.php builds an execAsync() command line by string concatenation, single-quoting each argument but never calling escapeshellarg(). A ' in any of the three interpolated values ($users_id, $m3u8, $obj-\u003eliveTransmitionHistory_id) closes the quoted token and lets the attacker append arbitrary commands.","aliases":["GHSA-xw67-cg5f-4m2r"],"modified":"2026-08-12T03:51:37.785608702Z","published":"2026-05-29T13:14:02.663Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-78"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45578.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45578.json"},{"type":"ADVISORY","url":"https://github.com/WWBN/AVideo/security/advisories/GHSA-xw67-cg5f-4m2r"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45578"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/wwbn/avideo","events":[{"introduced":"0"},{"last_affected":"2386f39caea1d2ef36267b252fa76af283294623"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"29.0"}],"source":["AFFECTED_FIELD","CPE_RANGE"],"cpe":"cpe:2.3:a:wwbn:avideo:*:*:*:*:*:*:*:*"}}],"versions":["29.0","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-2026-45578.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
