CVE-2026-84173Public exploit

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.
