LiteSpeed Cache is a popular site acceleration plugin for WordPress that, as the name implies, comes with advanced caching functionality and optimization features. It's installed on over six million sites.

The newly identified issue, per Patchstack, is rooted in a function named is_role_simulation and is similar to an earlier flaw that was publicly documented back in August 2024 (CVE-2024-28000, CVSS score: 9.8).

It stems from the use of a weak security hash check that could be brute-forced by a bad actor, thus allowing for the crawler feature to be abused to simulate a logged-in user, including an administrator.

The vulnerability, tracked as CVE-2024-50550 (CVSS score: 8.1), has been addressed in version 6.5.2 of the plugin.
