CVE-2026-2894Public exploitNetwork attack vector

Username disclosure via unvalidated password-recovery cookie

Published Feb 21, 2026 · Updated Feb 21, 2026

Information disclosure in FunAdmin 7.1.0-rc1 through 7.1.0-rc4 allows remote attackers to read another member's username. The password-recovery template passes the user-controlled forget_uid cookie directly to getMember and renders the returned username whenever forget_code is merely present. No authentication is required; exploitation needs crafted cookies and a reachable forget page, and the demonstrated disclosure is limited to usernames.
