{"affected":[{"product":"AVideo-Encoder","source":"CNA: GitHub_M","vendor":"WWBN","versions":[{"status":"affected","version":"< 8.1.0"}]}],"cveId":"CVE-2026-61567","cwes":["CWE-78"],"description":"AVideo is a video-sharing Platform. 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.","epss":{"date":"2026-11-02","percentile":0.44518,"score":0.00525},"exploits":[{"kind":"exploit","source":"ADP: CISA-ADP","url":"https://github.com/WWBN/AVideo-Encoder/security/advisories/GHSA-rf63-6vwm-wv8p"}],"kev":null,"metrics":[{"score":10,"severity":"critical","source":"CNA: GitHub_M","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"}],"modifiedAt":1793664525735,"publishedAt":1793223828515,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/WWBN/AVideo-Encoder/security/advisories/GHSA-rf63-6vwm-wv8p"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/WWBN/AVideo-Encoder/commit/99b8ad9b66fe5726cababbe29dce9d9695131caa"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/WWBN/AVideo-Encoder/releases/tag/v8.1.0"},{"source":"ADP: CISA-ADP","tags":["exploit"],"url":"https://github.com/WWBN/AVideo-Encoder/security/advisories/GHSA-rf63-6vwm-wv8p"}],"remediation":[],"revision":"6a0230fa1c6086f3ba11ed861f0ca132b5fdb8ecec51bf6cb7870d11abd32f57","sources":[{"modifiedAt":1793664525735,"name":"CNA: GitHub_M","retrievedAt":1793668147887,"url":"https://www.cve.org/CVERecord?id=CVE-2026-61567"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793668151728,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-61567"}],"ssvc":{"assessedAt":1793664492399,"automatable":"yes","exploitation":"poc","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"AVideo-Encoder: unauthenticated command execution through streamer login trust","updatedAt":1793668151728}
