Upgrade phpmyfaq/phpmyfaq to version 4.2.0-beta or higher.
Overview
phpmyfaq/phpmyfaq is a FAQ system for PHP and MySQL, PostgreSQL and other databases
Affected versions of this package are vulnerable to Improper Authentication via resolveLocalLogin in the Keycloak authentication flow, where an existing local account can be resolved by matching the preferred_username or email claim from a Keycloak token rather than requiring a stored Keycloak subject (sub) link. An attacker who controls a Keycloak identity with a preferred_username or email claim that collides with an existing local account can authenticate as that local account without ever having proved ownership of it, effectively taking over the account.
