October System module has a Reflected XSS via X-October-Request-Handler Header

Impact

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.

Patches

This issue has been patched in v3.5.15.
