Technical details
The vulnerability is a command injection flaw in the NewGenericDownload function located in server/internal/downloaders/generic.go. The params argument is passed to a downloader without proper validation or sanitization, allowing shell metacharacters and command separators to be executed. The attack is remotely exploitable over the network with no authentication required. An attacker can execute arbitrary commands with the privileges of the yt-dlp-web-ui process. The fix (commit c7ad3bd79c7c520a7d17e7f2ba19d962be8e7897) implements parameter whitelisting to restrict allowed arguments.
