WPCode – Insert Headers and Footers + Custom Code Snippets – WordPress Code Manager < 2.4.0 - Unauthenticated Snippet Safe Mode Bypass
The WPCode – Insert Headers and Footers + Custom Code Snippets – WordPress Code Manager plugin for WordPress is vulnerable to Bypass Vulnerability in all versions up to 2.4.0. This is due to insufficient verification of the login page check in wpcode_is_wplogin(), allowing any unauthenticated request with the safe mode parameter to bypass snippet execution. This makes it possible for unauthenticated attackers to disable all automatically inserted snippets for their own requests by triggering safe mode without authentication.
