Cluster state disclosure and modification via wildcard matching
Published Sep 7, 2026 · Updated Sep 8, 2026
Incorrect authorization in Eclipse Ankaios 0.5.1 through 1.0.1 allows attackers controlling a managed workload to read or replace cluster state. AllowPathPattern::matches skips the short-path check for a leading wildcard, and match_rule_with_path accepts an empty path after zero zip comparisons. Exploitation requires a managed workload with Control Interface access and a multi-segment StateRule beginning with a wildcard; the result is confined to unauthorized cluster-state disclosure and modification.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
