Privilege Escalation in LiteSpeed User-End cPanel Plugin redisAble Function

IdentifiersCVE-2026-48172CWE-266· Incorrect Privilege Assignment

CVE-2026-48172 is a critical privilege-escalation vulnerability in the LiteSpeed User-End cPanel Plugin affecting versions 2.3 through 2.4.4, and more generally versions before 2.4.5. The flaw is associated with incorrect privilege assignment and improper handling of the plugin’s Redis enable/disable functionality, exposed through the lsws.redisAble / redisAble JSON API path available to authenticated cPanel users. Reporting also describes the issue as involving a UNIX symlink following weakness in the Redis feature handling path. A low-privileged authenticated cPanel user, including a compromised shared-hosting tenant account or an attacker with FTP or web-shell access to such an account, can abuse this functionality to cause arbitrary scripts to execute with elevated privileges, potentially as root. The issue has been confirmed as actively exploited in the wild in May 2026.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation can result in full privilege escalation from a normal cPanel user context to root on the underlying Linux hosting server. This enables complete compromise of confidentiality, integrity, and availability of the host and all co-located tenants in shared-hosting environments. Reported post-exploitation activity includes arbitrary script execution as root, full administrative control of the server, malware deployment, persistence establishment, configuration tampering, access to other customers’ data, and observed use in the wild to deploy Mirai botnet variants and the Sorry ransomware strain.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, uninstall the user-end cPanel plugin to remove exposure. LiteSpeed provided the command /usr/local/lsws/admin/misc/lscmctl cpanelplugin --uninstall for this purpose. Restrict access to cPanel/WHM interfaces by source IP where feasible, especially in shared-hosting environments. Hunt for exploitation by searching cPanel logs for redisAble API calls, e.g. grep -rE "cpanel_jsonapi_func=redisAble" /var/cpanel/logs /usr/local/cpanel/logs/ 2>/dev/null. If matches are found, investigate the source IPs, block suspicious addresses, review system logs for follow-on activity, and assess for root-level persistence such as unexpected privileged users, cron jobs, SSH keys, modified binaries, web shells, and unusual outbound connections.

Remediation

Patch, then assume compromise.

Upgrade the LiteSpeed User-End cPanel Plugin to a fixed release immediately. The vulnerability is fixed in version 2.4.5, and the vendor-recommended minimum version is 2.4.7. Multiple sources also recommend upgrading to LiteSpeed WHM Plugin 5.3.1.0 bundled with cPanel plugin 2.4.7 or later as the preferred hardened release. Verify the actual deployed plugin version on each host rather than relying only on inventory records, and review affected systems for signs of compromise after patching.
