CVE-2026-48172 is a critical privilege-escalation vulnerability in the LiteSpeed User-End cPanel Plugin affecting versions 2.3 through 2.4.4, and more generally versions before 2.4.5. The flaw is associated with incorrect privilege assignment and improper handling of the plugin’s Redis enable/disable functionality exposed through the lsws.redisAble JSON API endpoint. Because this endpoint is available to authenticated cPanel users, a low-privileged cPanel account can abuse the vulnerable functionality to trigger execution of arbitrary scripts with elevated privileges, potentially as root. The issue is particularly severe on shared hosting infrastructure because compromise of a single tenant account can be leveraged to take control of the underlying server and affect other hosted customers. Active exploitation was reported in May 2026.
