What is CVE-2026-106033?
CVE-2026-106033 is a medium-severity cross-site scripting vulnerability in Red Hat Ansible Automation Platform 2, published on 6 Oct 2026. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Official description
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. The platform includes built-in URL validation functions designed to block malicious URI schemes (such as javascript: and data:) as well as off-site or protocol-relative redirects, this specific route bypasses those controls. Consequently, 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.
