Overview

AI description

Automated description summarized from trusted sources.

CVE-2026-48172 is a privilege escalation vulnerability found in the LiteSpeed User-End cPanel Plugin, affecting versions between 2.3 and 2.4.4. This flaw stems from an incorrect privilege assignment and a logic error within the plugin's `lsws.redisAble` JSON-API endpoint. The vulnerability allows any authenticated cPanel user, including those with low privileges or compromised accounts, to execute arbitrary scripts with root permissions, potentially leading to full server control. This vulnerability has been actively exploited in the wild. A patch was released in version 2.4.5 of the LiteSpeed User-End cPanel Plugin, with further updates in version 2.4.7, which is bundled with WHM plugin version 5.3.1.0. Detection of potential exploitation can be performed by searching cPanel logs for the string "cpanel_jsonapi_func=redisAble".

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.
