CVE-2022-4731Network attack vector

Cross-site scripting via trusted page titles

Published Dec 25, 2022 · Updated Aug 3, 2024

Cross-site scripting in the MyApnea 29.0 Title Handler allows remote authenticated users to alter rendered page content. Five Haml layouts mark the concatenated page title as HTML-safe, preventing Rails from escaping attacker-controlled title markup before rendering it. A high-privileged account must supply a crafted title and another user must view the affected page; execution is limited to that viewer's browser context.
