Prior to 8.1.0, the live-streaming endpoint `view/videosListToLive.php` accepts an attacker-named streamer in `webSiteRootURL`, calls `Login::run` in `objects/Login.php`, and trusts the returned JSON as session state. An unauthenticated remote attacker who can host an HTTP service reachable by the encoder can self-grant `isLogged` and `canStream` without legitimate credentials. The endpoint requires only nonempty `playlists_id` and `APISecret` values; `APISecret` is forwarded rather than checked against a stored secret. This path never calls `Streamer::isURLAllowed` and therefore works regardless of the operator's streamer allowlist. It fetches a second attacker-controlled video-list response and interpolates `videos[].path` without shell argument escaping into `ffprobe` and `ffmpeg` commands passed to `exec`; `isAudio` calls `isVideo` to reach the `ffprobe` command. Paths containing shell delimiters execute arbitrary operating-system commands as the web-server user. The request filter does not inspect the video-list JSON. This can disclose database and stored streamer credentials, compromise the upstream platform using those credentials, modify files owned by the web-server user, establish persistence, and deny encoder service. This issue is fixed in version 8.1.0.","score":10,"severity":"critical","published":"2026-10-28T21:43:48.515Z","modified":"2026-10-28T21:43:48.515Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"WWBN","name":"AVideo-Encoder","platforms":[],"versions":[{"version":"< 8.1.0","status":"affected"}],"cpes":[],"source":"GitHub_M","url":"https://www.cve.org/CVERecord?id=CVE-2026-61567"}],"remediation":[],"references":["https://github.com/WWBN/AVideo-Encoder/security/advisories/GHSA-rf63-6vwm-wv8p","https://github.com/WWBN/AVideo-Encoder/commit/99b8ad9b66fe5726cababbe29dce9d9695131caa","https://github.com/WWBN/AVideo-Encoder/releases/tag/v8.1.0"],"sources":[{"name":"CVE","id":"CVE-2026-61567","modified":"2026-10-28T21:43:48.515Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-61567"}],"assessments":[{"source":"GitHub_M","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","score":10}],"sourceAffected":[],"observedAt":"2026-10-29T14:41:01.747Z","kev":{"status":"not-listed","checkedAt":"2026-10-31T11:20:32.820Z"},"coverage":[{"source":"NVD","status":"available","checkedAt":"2026-10-28T22:50:33.148Z","attemptedAt":"2026-10-28T22:50:33.148Z"},{"source":"GHSA","status":"no-result","checkedAt":"2026-10-28T22:50:32.873Z","attemptedAt":"2026-10-28T22:50:32.873Z"},{"source":"EUVD","status":"available","checkedAt":"2026-10-28T22:50:32.279Z","attemptedAt":"2026-10-28T22:50:32.279Z"},{"source":"EPSS","status":"no-result","checkedAt":"2026-10-28T22:50:31.958Z","attemptedAt":"2026-10-28T22:50:31.958Z"}],"evidence":[{"source":"ENISA EUVD","id":"EUVD-2026-112508","url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-112508","modified":"Oct 28, 2026, 9:43:48 PM","score":10,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","checkedAt":"2026-10-28T22:50:32.279Z"},{"source":"NVD","id":"CVE-2026-61567","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-61567","modified":"2026-10-28T22:17:15.900","score":10,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","checkedAt":"2026-10-28T22:50:33.148Z"}],"aiSummary":{"text":"AVideo-Encoder versions prior to 8.1.0 are vulnerable to unauthenticated command execution through the live-streaming endpoint.
