AI-suggested

Red Hat has published an advisory for this vulnerability. Since the certificate issued has a hard-coded ten-year validity and no revocation mechanism, mitigation requires rotating the mesh CA across the entire fleet to revoke affected certificates. Administrators should follow Red Hat's official guidance in the advisory to perform this rotation. No other immediate action is required as the vulnerability is restricted to system administrators and does not allow remote code execution.

Description

CVE-2026-84716 is a moderate severity vulnerability in Red Hat Ansible Automation Platform 2.5 for RHEL 8 affecting the automation-controller's instance install-bundle endpoint. It allows a system administrator to obtain a long-lived, non-revocable X.509 certificate signed by the receptor mesh certificate authority by exploiting case sensitivity inconsistencies in hostname validation. This certificate can be used to impersonate or intercept TLS traffic within the receptor mesh in managed or hosted deployments. The flaw does not allow direct remote code execution.
