AI-suggested
A patch is available for this vulnerability. Users should upgrade Consul and Consul Enterprise to versions 1.20.0 or later where this issue is fixed. Until patched, users should be aware of the risk of reflected XSS due to missing Content-Type headers in server responses.
Description
Consul and Consul Enterprise versions from 1.4.1 up to but not including 1.20.0 are affected by a reflected cross-site scripting (XSS) vulnerability. This occurs because the server response does not explicitly set a Content-Type HTTP header, allowing user input to be misinterpreted and reflected in the response. The vulnerability has a medium severity rating and a patch is available to address the issue.
