Overview

This vulnerability affects the Roundcube webmail component integrated with cPanel.

  2. Apply any security patches provided by cPanel for this specific issue
  3. Monitor system logs for any suspicious activity related to Roundcube or SQLite operations
  4. Consider temporarily disabling Roundcube if immediate updates are not possible
  5. Implement proper file system permissions and access controls as additional security layers
