What is CVE-2026-61569?
CVE-2026-61569 is a high-severity vulnerability in WWBN AVideo-Encoder, published on 28 Oct 2026.
Official description
AVideo is a video-sharing Platform. Prior to 8.1.0, the unauthenticated streamer login at `objects/login.json.php` passes the `user` parameter to `Streamer::get` in `objects/Streamer.php`, where it is interpolated into a single-quoted MariaDB SELECT without parameterization or escaping. Although `objects/security.php` strips literal single quotes, `html_entity_decode` in `objects/Login.php` restores entity-encoded quotes before the query. The supplied `siteURL` must pass the streamer allowlist, which allows all sites when empty by default, and an attacker-hosted login response must set `canUpload` or `isAdmin` to reach `Streamer::createIfNotExists`. That function calls `Streamer::get` before its additional allowlist check. UNION results are exposed through `streamers_id`, while failures return the rendered query and MariaDB error. An attacker can read arbitrary encoder database data, including stored upstream streamer credentials, allowlist configuration, and queue records, without encoder credentials. Stacked statements are not permitted by the mysqli driver and the tested database account lacks global FILE privilege, so the demonstrated vector is bounded to reads rather than server-side file writes. Stolen streamer credentials can provide continued upstream access until rotated. This issue is fixed in version 8.1.0.
