CVE-2026-109131: Red Hat Ansible Automation Platform stored XSS in Hub documentation renderer

CVE-2026-109131 · Severity: medium · CVSS 5.4 · Published 2026-10-15

The Ansible Automation Platform UI includes a documentation viewer for collections that fails to validate URL schemes before rendering links. An attacker can inject malicious JavaScript URLs into collection documentation, which executes with the authenticated user's privileges when that user views the documentation page. This could allow an attacker to steal session cookies, modify content, or perform unauthorized actions on behalf of the victim.

Technologies: Red Hat Ansible Automation Platform. Vendors: Red Hat.

Technical details

This is a stored cross-site scripting vulnerability in the DocumentationParsers.tsx component's formatPartURL function, which renders documentation URLs without restricting the URL protocol/scheme. An attacker can craft collection documentation containing javascript: URLs that execute arbitrary code in the browser with the same origin privileges as the Hub UI. The vulnerability requires an authenticated user to view and click the malicious link in the documentation page.
