CVE-2026-90960 Details
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.
A vulnerability allowing sensitive information exposure has been identified in the Seraphinite Accelerator plugin for WordPress, in all versions prior to and including 2.29.24. The issue arises in the WP_Object_Cache::_getFilePath method, where unauthenticated attackers can access complete WordPress user records. This includes plaintext usernames, email addresses, hashed passwords, and activation keys. The data is extracted from predictable gzip-serialized cache files located in the wp-content/cache/seraphinite-accelerator/oc/g/users/g/<USER_ID>.dat.gz. Exploitation requires the plugin's Object Cache feature to be enabled and involves first caching the target user record, such as through an unauthenticated REST API request, before retrieving the cached file.
Users are advised to update the Seraphinite Accelerator plugin to version 2.29.25 or a newer patched version.
