Description

The Seraphinite Accelerator plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.29.24 via the WP_Object_Cache::_getFilePath. This makes it possible for unauthenticated attackers to extract complete WordPress user records — including plaintext user_login, user_email, hashed user_pass, and user_activation_key — from predictable gzip-serialized cache files at wp-content/cache/seraphinite-accelerator/oc/g/users/g/<USER_ID>.dat.gz. This vulnerability is only exploitable when the plugin's Object Cache feature is enabled, and requires the attacker to first trigger caching of the target user record (e.g., via an unauthenticated REST API request) before retrieving the resulting cache file.
