CVE-2026-48172
CWE-266Published: May 21, 2026· Updated: May 26, 2026
Official 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.
Risk Analysis
This critical vulnerability in the LiteSpeed User-End cPanel Plugin before version 2.4.5 allows for privilege escalation, potentially to root. The issue stems from mishandling of Redis enable/disable features. With a CVSS score of 9.8, this vulnerability poses a severe risk of complete system compromise.
This vulnerability is actively exploited in the wild, as observed in May 2026, and is listed in CISA's KEV catalog. Attackers can exploit this remotely without authentication due to the network attack vector and low attack complexity.
Upgrade the LiteSpeed User-End cPanel Plugin to version 2.4.7 or higher. Regularly monitor system logs for suspicious activity related to Redis enable/disable features and block any unauthorized IP addresses.
Technical Analysis
CVE-2026-48172 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
CISA has added CVE-2026-48172 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
