schaffnern has discovered a vulnerability in the Absolute Privacy plugin for WordPress, which can be exploited by malicious people to bypass certain security restrictions.

The vulnerability is caused due to an error within the "abpr_authenticateUser()" function in wp-content/plugins/absolute-privacy/functions.php, which prevents the password from being verified. This can be exploited to bypass the authentication mechanism and gain administrative access to the application.

The vulnerability is confirmed in version 2.0.5. Other versions may also be affected.
