CVE-2025-25207

Service interruption via unbounded post-authorization callbacks

Published Jun 9, 2025 · Updated Mar 26, 2026

Uncontrolled resource consumption in Red Hat Connectivity Link 1.0.1 allows remote authenticated users to interrupt the Authorino service. The AuthPolicy callback list accepts a large number of post-authorization HTTP actions without limiting their consumption by the single Authorino instance. Developer-persona access is required to edit the policy; processing the callbacks can stop authorization-policy evaluation across the cluster.
