Description

WWBN AVideo is an open source video platform. In versions up to and including 26.0, the restreamer endpoint constructs a log file path by embedding user-controlled `users_id` and `liveTransmitionHistory_id` values from the JSON request body without any sanitization. This log file path is then concatenated directly into shell commands passed to `exec()`, allowing an authenticated user to achieve arbitrary command execution on the server via shell metacharacters such as `$()` or backticks. Commit 99b865413172045fef6a98b5e9bfc7b24da11678 contains a patch.
