October CMS is susceptible to remote code execution. In affected versions, user input is not properly sanitized before rendering. An authenticated user with the permissions to create, modify, and delete website pages can bypass cms.safe_mode and cms.enableSafeMode in order to execute arbitrary code. This affects admin panels that rely on safe mode and restricted permissions.
