cPanel LiteSpeed Web Server Vulnerability Allows Shared Server Users to Gain Root-Level Access
Critical LiteSpeed Enterprise flaw fixed in 6.3.7 lets low-privilege shared-hosting users escalate to root and bypass CageFS.
cPanel issued an urgent advisory for a critical privilege escalation in LiteSpeed Web Server Enterprise versions before 6.3.7, allowing a low-privilege shared-hosting account to gain root-level server control and bypass tenant isolation controls including CloudLinux CageFS. Root access would let attackers access other hosted sites, steal databases and credentials, deploy phishing pages, and install backdoors. Administrators are urged to upgrade to 6.3.7 immediately via lsup.sh and to review privileged account activity, cron jobs, SSH keys, and system binaries; no CVE identifier was published.

- Flaw bypasses CageFS and undermines multi-tenant isolation
- Fixed in LiteSpeed Enterprise 6.3.7; upgrade urged immediately
- Single compromised account could expose thousands of co-hosted websites
- No CVE identifier published in the advisory
