LiteSpeed cPanel Plugin Remote Code Execution | MSSP Advisory

CISA issued an emergency directive giving federal agencies four days to patch a critical vulnerability in the LiteSpeed cPanel user-end plugin that attackers are actively exploiting. The flaw allows remote code execution on web servers running this specific cPanel plugin. Federal agencies must patch or disconnect affected systems by the deadline.

Web hosting clients running cPanel with the LiteSpeed plugin face immediate compromise risk, and MSSPs managing these environments become liable if breaches occur during active exploitation periods. Your own infrastructure becomes a target if you run cPanel environments for internal tools or client hosting services. CISA emergency directives signal that threat actors have reliable exploit code and are hitting targets successfully.
