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.
