What fixes it

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

phpMyFAQ before 4.1.9 and 4.2.0-alpha before 4.2.0-beta contains a cross-site request forgery vulnerability in the Elasticsearch and OpenSearch administration API endpoints, which do not validate a CSRF token for the create, drop, and import actions. Attackers can lure a user with CONFIGURATION_EDIT permission to a malicious page that triggers these actions, deleting search indexes, forcing re-indexing, or exhausting resources.
