Summary
In Red Hat Ansible Automation Platform's automation-controller, four debug views that trigger the internal task, dependency, and workflow schedulers are accessible to any user, including unauthenticated clients, because their URL routing is not gated on the debug setting. An unauthenticated remote attacker can repeatedly invoke these endpoints to acquire the cluster-wide scheduler advisory lock, causing real scheduler runs to be skipped and stalling job dispatch for all tenants while consuming controller web workers.
Risk Assessment
An unauthenticated attacker can stall job processing across the entire Ansible Automation Platform cluster, causing automation outages for all tenants. The debug root view also discloses the list of debug endpoints to unauthenticated callers.
Recommendation
Upgrade Red Hat Ansible Automation Platform to a version containing the fix and, where possible, restrict network access to the debug endpoints and monitor for unusual calls to these paths.

- CVE-2026-84499High
A flaw was found in Red Hat Ansible Automation Platform's automation-controller. Survey questions of type password are write-only and stored encrypted, displayed only as a placeholder on read. When a schedule or workflow job template node is revalidated against a tightened survey specification, the controller decrypts the stored password and includes its plaintext value in the minimum/maximum length validation error message returned in the HTTP response. A user with the delegated JobTemplate Admin role can tighten the survey length constraint and trigger revalidation of a schedule or node created by another, higher-privileged user, thereby recovering that user's stored password in plaintext.
Original NVD description (English source)
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.
