Summary

CVE-2026-84486 is a high-severity Active Debug Code (CWE-489) vulnerability. Its CVSS base score is 8.2 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 42th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to CM-2 (Baseline Configuration) and CM-7 (Least Functionality) — see the control section below for these in your framework.

Vulnerability Data

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.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Baseline configuration defines the approved production state that must exclude active debug code.

Least functionality explicitly prohibits enabling unnecessary debug or diagnostic features in production builds.

Documented development standards and tools can require removal of debug code before release.

Security-integrated SDLC processes ensure debug artifacts are stripped prior to deployment.

PR.PS-06 partial match
prevents

Secure SDLC practices directly require removal of debug code before release, covering most of this weakness while the control addresses many other development issues.

prevents

Secure development life cycle mandates removal of debug code before release.

prevents

Secure coding standards explicitly prohibit leaving debug code active in production.

finds

Security testing in development and acceptance catches active debug code before deployment.

prevents

Separation of environments reduces risk of debug code reaching production but does not directly address its removal.

prevents

Change management can enforce removal of debug code as part of release gates.

prevents

Configuration management can disable or remove debug features through hardened baselines.
