{"id":"CVE-2026-45578","aliases":["GHSA-xw67-cg5f-4m2r"],"url":"https://o3.security/vulnerability/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->liveTransmitionHistory_id) closes the quoted token and lets the attacker append arbitrary commands.","published":"2026-05-29T13:14:02.663Z","modified":"2026-08-12T03:51:37.785608702Z","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":{"score":0.00318,"percentile":0.24336,"asOf":"2026-08-12"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"WWBN/AVideo","fixedVersion":null}],"fix":null,"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:37.785608702Z"}}
