What to do

AI-suggested

Red Hat advises that the issue only affects configurations where client certificates are optional; environments enforcing strict client certificate requirements or disabling them entirely at the transport layer are not vulnerable. Users should review their grpc-js client certificate configurations and avoid optional client certificate settings where possible until a fix is released. Monitor Red Hat advisories for updates and patches addressing this issue.

Description

A security advisory from Red Hat addresses vulnerabilities in the Ansible Automation Platform 2.2, specifically related to the Ansible Automation Portal delivered as a bootable container image. One notable vulnerability (CVE-2026-101916) involves improper certificate validation in grpc-js, allowing an unauthenticated remote attacker to bypass access control when client certificates are optionally configured. This can lead to unauthorized access to protected services. The advisory does not list fixed versions or patches yet and highlights that exploitation requires specific configuration conditions.
