CVE-2024-25637: October System module has a Reflected XSS via X-October-Request-Handler Header

June 26, 2024

The X-October-Request-Handler Header does not sanitize the AJAX handler name and allows unescaped HTML to be reflected back. There is no impact since this vulnerability cannot be exploited through normal browser interactions. This unescaped value is only detectable when using a proxy interception tool.
