Recommendation: Monitor — no exploitation signal at the moment.
Insecure default settings of Portainer CE grant regular (non-admin) users privileges that allow host filesystem access and host-level code execution. An authenticated non-administrative user with endpoint access can exploit these settings to read host files or obtain root equivalent
access on the host.
