LiteSpeed cPanel Plugin CVE-2026-48172 Exploited to Run Scripts as Root

A critical vulnerability in the LiteSpeed cPanel plugin, tracked as CVE-2026-48172, enables cPanel users to execute arbitrary scripts with root privileges on affected web hosting servers. The flaw affects plugin versions 2.3 through 2.4.4 and represents a severe privilege escalation vector in shared hosting environments where multiple customers share a single server. A successful exploit could allow one hosting customer to compromise all other accounts on the server, access their data, and potentially pivot to the hosting provider's infrastructure. Web hosting providers using LiteSpeed with cPanel should immediately update to patched plugin versions and audit their servers for signs of unauthorized privilege escalation. The vulnerability highlights the concentration risk in hosting control panel ecosystems where a single plugin flaw can cascade to thousands of servers.
