CVE-2023-1883Public exploitNetwork attack vector

Unauthorized comments via missing inactive-record check

Published Apr 5, 2023 · Updated Feb 10, 2025

Improper access control in phpMyFAQ before 3.1.12 allows remote authenticated users to post comments on inactive FAQ or news records. The ajaxservice.php comment-save path checks whether comments are enabled but does not reject a target record whose active flag is disabled. A registered account and an inactive record with comments enabled are required; exploitation writes a comment to content intended to remain unpublished.
