CVE-2023-1875Network attack vector

Authenticated script execution via unencoded profile fields

Published Apr 22, 2023 · Updated Feb 4, 2025

Stored XSS in phpMyFAQ before 3.1.12 allows remote authenticated users to execute script in another user's browser through user profile fields. In admin/user.php, display_name and last_modified POST values were accepted with FILTER_UNSAFE_RAW instead of conversion to HTML entities before storage and rendering. An account able to submit those fields is required, and the resulting script runs in the phpMyFAQ origin when the stored values are viewed.
