CVE-2023-30869: 
WordPress vulnerability analysis and mitigation

CVE-2023-30869 is a critical security vulnerability discovered in the Easy Digital Downloads (EDD) WordPress plugin affecting versions 3.1 through 3.1.1.4.1. The vulnerability was discovered by Nguyen Anh Tien on April 21st, 2023, and was publicly disclosed on May 2nd, 2023. This Improper Authentication vulnerability received a CVSS score of 9.8, indicating its critical severity (Patchstack Advisory).

The vulnerability stems from an improper authentication mechanism that allows any user, regardless of their authentication status, to execute any action registered with the prefix 'edd_'. This prefix is present in the password reset function, which lacks proper validation for the password reset key. Instead of validating the reset key, the function directly changes the password for the given user, bypassing crucial security checks (Security Online).

The vulnerability affects over 50,000 active installations of the Easy Digital Downloads plugin. It enables attackers to reset passwords for any user, including administrators, as long as they know the targeted username. This could lead to complete website compromise through unauthorized administrative access (Security Online).

The vulnerability has been patched in version 3.1.1.4.2 of the Easy Digital Downloads plugin. The fix prevents the password reset function from being called directly and adds validation measures to ensure the legitimacy of the password reset key. Users are strongly advised to update to version 3.1.1.4.2 or later immediately (Patchstack Advisory).
