This image carries significant risk; production deployment is highly discouraged without strict compensating controls. An attacker could achieve remote code execution on all flannel nodes if the (non-default) Extension backend is enabled, or cause denial of service via OpenSSL vulnerabilities. Using a non-Extension backend (vxlan or wireguard) fully eliminates CVE-2026-32241. Note that most OpenSSL DoS issues require specific conditions (e.g., delta CRL processing or CMS data) that are unlikely in normal flannel operation. Remediating the top CVEs is strongly advised before any production use.
