Advisory
Source description from Wordfence Intelligence, credited to Ananda Dhakal.
The All-In-One Security (AIOS) – Security and Firewall plugin for WordPress is vulnerable to Bypass Vulnerability in all versions up to, and including, 5.4.8. This is due to missing validation on the udrpc_action POST format parameter, allowing requests with format values below 2 to be processed without restriction. This makes it possible for authenticated attackers, with subscriber-level access and above, to bypass security controls by sending UDRPC action requests with a format value below 2, gaining unauthorized access to privileged functionality.
