CVE-2026-78051Public exploitNetwork attack vector

Cookie disclosure via unrestricted download route

Published Aug 22, 2026 · Updated Aug 22, 2026

Information disclosure in Alex Shnitman MeTube 2026.06.10 and earlier allows remote attackers to read uploaded cookies via HTTP. The download route serves files beneath /downloads without excluding the .metube state directory, so /download/.metube/cookies.txt returns the stored file. A cookie file must be present; default deployments require no authentication, while reverse-proxy authentication still exposes it to authenticated users, enabling theft of stored account cookies.
