CVE-2026-48172
CRITICAL
CVSS 10.0
No EPSS data
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.

"value": "LiteSpeed User-End cPanel plugin anterior a 2.4.5 permite la escalada de privilegios (posiblemente a root), tal como fue explotado en la naturaleza en mayo de 2026. La detecci\u00f3n se realiza mejor a trav\u00e9s de una l\u00ednea de comandos de grep -rE 'cpanel_jsonapi_func=redisAble' /var/cpanel/logs /usr/local/cpanel/logs/ 2>/dev/null en Bash. Si no obtiene ninguna salida, no ha sido afectado por la explotaci\u00f3n de la vulnerabilidad. Si hay salida, le recomendamos que examine las direcciones IP en la lista, determine si son direcciones IP v\u00e1lidas y, si no lo son, bloqu\u00e9elas. Para determinar el da\u00f1o causado, examine los registros del sistema para ver el uso por parte de las direcciones IP detectadas. El problema est\u00e1 relacionado con el manejo incorrecto de las funciones de habilitaci\u00f3n/deshabilitaci\u00f3n de Redis. La versi\u00f3n m\u00ednima recomendada es 2.4.7."
