- Exploited in the wild
- Can lead to full server control
- Affects cPanel users
Attack Path
How an attacker could exploit the issue
An attacker can exploit this vulnerability by leveraging improper handling of Redis features within the LiteSpeed User-End cPanel Plugin. This could allow any authenticated cPanel user to escalate their privileges, potentially gaining root access on the server to execute arbitrary commands. The vulnerability was actively exploited in the wild in May 2026.
- Exploitable by authenticated cPanel users.
- Targets Redis enable/disable functionality.
- Assumes existing cPanel account access.

Priority actions
Operational Fix
Recommended remediation, mitigation, and detection steps
Teams must prioritize upgrading the LiteSpeed cPanel plugin to version 2.4.7 or later immediately due to active exploitation and critical privilege escalation risks. If an immediate upgrade is not feasible, isolate affected services to prevent further compromise while preparing to patch.
- Upgrade LiteSpeed cPanel plugin to 2.4.7+.
- Monitor logs for suspicious commands.
- Isolate vulnerable servers if patching is delayed.
