LiteSpeed cPanel Plugin Privilege Escalation Vulnerability

KEVCRITICAL 10.0EPSS 1.01%

Does this matter?

Known to be exploited in the wild (CISA KEV, CISA remediation deadline 29 May 2026). Treat as an emergency change: patch or isolate now, then hunt for prior compromise.

Description

LiteSpeed User-End cPanel Plugin before 2.4.5 allows privilege escalation (possibly to root), as exploited in the wild in May 2026. Detection is best done via a command line of grep -rE "cpanel_jsonapi_func=redisAble" /var/cpanel/logs /usr/local/cpanel/logs/ 2>/dev/null in Bash. If you get no output, you have not been hit with exploitation of the vulnerability. If there is output, we recommend you examine the IP addresses in the list, determine if they are valid IP addresses, and if not, block them. To determine damage done, examine the system logs for use by the detected IP addresses. The issue is related to mishandling of Redis enable/disable features. The recommended minimum version is 2.4.7.
