The issue arises from hardcoded passwords within the 'fb_ajax_login_or_register' and 'google_ajax_login_or_register' functions, mapped to CWE-798 (Use of Hard-coded Credentials). Published on 2025-10-16, it carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), denoting critical severity due to its potential for high-impact remote exploitation.
