CVE-2026-84683 PUBLISHED CVSS 8.7 HIGH

Reported by redhat · Published September 23, 2026

A flaw was found in Red Hat Ansible Automation Platform's automation- controller. The HTML view of job, ad hoc command, project update, and inventory update standard output escapes HTML metacharacters but does not remove ANSI terminal escape sequences before conversion to HTML. An ANSI OSC 8 hyperlink sequence in the output is expanded into an HTML anchor whose href is not scheme- filtered or escaped, so a low-privileged user who can produce output -- or an external party whose data a playbook echoes -- can embed a javascript: link that is rendered into a text/html response with no Content-Security-Policy. When a higher-privileged user views the output page and clicks the link, attacker- controlled JavaScript executes in their authenticated session, allowing actions as that user up to full platform takeover.
