CVE-2026-84486

Description

A flaw was found in Red Hat Ansible Automation Platform's automation- controller. Four debug views that trigger the internal task, dependency, and workflow schedulers are configured to allow any user (including unauthenticated clients) and are routed in production builds because their URL include is not gated on the debug setting. An unauthenticated remote attacker can repeatedly invoke these endpoints to acquire the cluster-wide scheduler advisory lock; because the legitimate scheduler acquires the same lock without waiting, the attacker causes real scheduler runs to be skipped, stalling job dispatch for all tenants, while also consuming controller web workers. The debug root view additionally discloses the list of debug endpoints to unauthenticated callers.
