The payload is decoded and its groups or roles are used as RBAC subjects. A self-minted token whose groups contain admin matches the built-in admin role, with no account and no RoleBinding. The attacker can open an exec or log session for a microservice or fog whose UUID they already know. HTTP routes are not affected: they verify the token before RBAC. Agent WebSockets verify the fog token and are not affected.\n\n## Affected\n\n- `eclipse_iofog >= 3.8.0 <= 3.9.1`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"midnight","depthScore":54,"depthScoreParts":{"impact":53.9,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
