CRITICAL 10.0

DescriptionNVD

The WP Directory Kit plugin for WordPress is vulnerable to authentication bypass in all versions up to, and including, 1.4.4 due to incorrect implementation of the authentication algorithm in the "wdk_generate_auto_login_link" function. This is due to the feature using a cryptographically weak token generation mechanism. This makes it possible for unauthenticated attackers to gain administrative access and achieve full site takeover via the auto-login endpoint with a predictable token.

Analysis

Technical ContextAI

An authentication bypass vulnerability allows attackers to circumvent login mechanisms and gain unauthorized access without valid credentials.

RemediationAI

A vendor patch is available — apply it immediately. Implement robust authentication mechanisms. Use multi-factor authentication. Review authentication logic for bypass conditions. Remove default credentials.
