CVE-2026-86836

Workload impersonation via attacker-owned control FIFOs

Published Sep 14, 2026 · Updated Sep 14, 2026

Path-reuse weakness in Eclipse Ankaios 0.1.0 through 1.0.2 allows local users to impersonate workloads through pre-created FIFOs. The agent derives predictable workload paths and reuses existing control FIFOs after checking only existence or file type, without validating ownership or permissions. Write access to the shared base directory is required; the impersonated workload's configured access can expose or modify cluster desired state.
