CVE-2026-109131 Red Hat CVE debrief

Who should care

Defenders responsible for Red Hat Ansible Automation Platform 2 deployments should assess exposure and prioritize patching or mitigation to prevent exploitation. This includes operators, platform administrators, vulnerability management teams, and security teams who need to verify affected versions, apply patches or mitigations, and monitor for suspicious activity in the Ansible Automation Platform UI.

Why it matters

A stored cross-site scripting issue in the Ansible Automation Platform UI requires defenders to verify affected versions, apply patches, and monitor for suspicious activity to prevent exploitation and potential data exposure.

• Potential script execution in the same origin as the Hub UI
• Possible unauthorized actions by authenticated users
• Required verification of affected versions and patching
• Potential data exposure or integrity issues

Technical summary

The Hub collection module documentation renderer in the unified Ansible Automation Platform UI renders a documentation URL part as a link without restricting the URL protocol/scheme. This allows an attacker to inject malicious JavaScript code via an unsafe URL scheme, which can be executed when another authenticated user views and activates the link in the collection documentation page. The issue affects Red Hat Ansible Automation Platform 2 deployments, requiring defenders to verify affected versions, apply patches, and monitor for suspicious activity to prevent exploitation and potential data exposure.

Defensive priority

Defenders should prioritize verifying the affected versions of Red Hat Ansible Automation Platform 2 and applying patches or mitigations to prevent exploitation.

Recommended defensive actions

• Verify the affected versions of Red Hat Ansible Automation Platform 2
• Apply patches or mitigations to prevent exploitation
• Monitor for suspicious activity in the Ansible Automation Platform UI
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
