CVE-2026-84486 is a vulnerability in Red Hat Ansible Automation Platform
Published on September 23, 2026
Automation-controller: automation-controller-container: automation-controller: unauthenticated debug scheduler-trigger endpoints (allowany, routed without debug guard) allow advisory-lock starvation of job dispatch (dos)
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.
Vulnerability Analysis
CVE-2026-84486 is exploitable with network access, and does not require authorization privileges or user interaction. This vulnerability is considered to have a low attack complexity. The potential impact of an exploit of this vulnerability is considered to have a small impact on confidentiality, a small impact on integrity, and a high impact on availability.

Weakness Type
Active Debug Code
The application is deployed to unauthorized actors with debugging code still enabled or active, which can create unintended entry points or expose sensitive information. A common development practice is to add "back door" code specifically designed for debugging or testing purposes that is not intended to be shipped or deployed with the application. These back door entry points create security risks because they are not considered during design or testing and fall outside of the expected operating conditions of the application.
