AI-suggested
To mitigate CVE-2025-6895, organizations should immediately update the Melapress Login Security plugin to a patched version once available. Until a patch is released, consider disabling the plugin to eliminate the attack vector. Implement additional access controls such as IP whitelisting or web application firewalls (WAFs) to detect and block suspicious authentication bypass attempts targeting the vulnerable function. Monitor authentication logs for unusual login patterns or access from unknown IP addresses. Restrict knowledge of user meta values by limiting access to user metadata and employing least privilege principles for administrative accounts. Conduct thorough security audits of WordPress installations to identify any signs of compromise. Employ multi-factor authentication (MFA) at the WordPress login level to add an extra layer of defense, although this may not fully prevent bypass if the plugin is exploited. Regularly back up site data and configurations to enable rapid recovery if compromise occurs. Engage with the plugin vendor or community to track patch releases and security advisories. Finally, educate site administrators about the risks and signs of exploitation to enhance early detection and response.
Description
The Melapress Login Security plugin for WordPress is vulnerable to Authentication Bypass due to missing authorization within the get_valid_user_based_on_token() function in versions 2.1.0 to 2.1.1. This makes it possible for unauthenticated attackers who know an arbitrary user meta value to bypass authentication checks and log in as that user.
