This high-severity CVE scores 8.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.5%, top 64% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
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.
