CVE-2026-75918Public exploitNetwork attack vector

Account takeover via reset tokens in tracking files

Published Aug 19, 2026 · Updated Aug 25, 2026

Information exposure in phpMyFAQ before 4.1.7 allows remote attackers to take over accounts via publicly readable tracking files. UserSession::userTracking() writes the raw reset-link query string, including the u, exp, and sig values, to a dated file inside the web root without access controls. Exploitation requires user tracking, enabled by the installer by default, and a target to open a valid reset link before the token expires or the password changes.
