A fix for this vulnerability is not explicitly stated in the provided data. Until a patch is available, it is recommended to disable the Object Cache feature of the Seraphinite Accelerator plugin to prevent exploitation.
Description
The Seraphinite Accelerator plugin for WordPress up to version 2.29.24 contains a vulnerability that allows unauthenticated attackers to access sensitive user information. This occurs through the plugin's Object Cache feature, where attackers can retrieve gzip-serialized cache files containing complete WordPress user records, including usernames, emails, hashed passwords, and activation keys. Exploitation requires triggering the caching of the target user record before accessing the cache file.
