CVE-2026-106033 Red Hat CVE debrief
A DOM-based Cross-Site Scripting (XSS) vulnerability exists in the Ansible Platform UI due to unvalidated input handling within the application's redirect route. Specifically, the application extracts a target destination from the next query parameter and directly assigns it to the browser's location.href without verifying its format or scheme. This allows an attacker to craft a malicious link that, when accessed by an authenticated user, causes arbitrary JavaScript to execute within the context of the user's session. The vulnerability has a medium severity and defenders should prioritize verifying exposure, restricting access, and implementing additional security controls.

Who should care
Defenders responsible for securing Ansible Automation Platform deployments, especially those with exposed UI interfaces, should assess their exposure and implement necessary security controls.
Why it matters
CVE-2026-106033 is a medium-severity DOM-based XSS vulnerability in the Ansible Automation Platform UI. Defenders should prioritize verifying exposure, restricting access, and implementing additional security controls.
- Authenticated users may be tricked into executing arbitrary JavaScript, potentially leading to session hijacking or other malicious activities
- Successful exploitation requires user interaction and authentication
- Remediation priority is medium, as the vulnerability is publicly known and may be targeted by attackers
- Further verification is needed to determine affected versions and remediation steps
Technical summary
The Ansible Platform UI is vulnerable to a DOM-based Cross-Site Scripting (XSS) attack due to unvalidated input handling in the redirect route. An attacker can craft a malicious link that, when accessed by an authenticated user, causes arbitrary JavaScript to execute within the context of the user's session. The vulnerability has a medium severity and defenders should prioritize verifying exposure, restricting access, and implementing additional security controls. The platform includes built-in URL validation functions designed to block malicious URI schemes.
Defensive priority
Defenders should prioritize verifying exposure of the Ansible Automation Platform UI, especially in environments where authenticated users may be tricked into accessing malicious links.
Recommended defensive actions
- Verify exposure of Ansible Automation Platform UI to untrusted networks
- Restrict access to the UI to trusted users and networks
- Implement additional security controls, such as input validation and content security policy
- Monitor for suspicious activity and implement incident response plan
- 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
Evidence notes
