NVD Description

Note: Versions mentioned in the description apply only to the upstream python3.14 package and not the python3.14 package as distributed by RHEL.

http.cookies.Morsel.js_output() returns an inline <script> snippet and only escapes " for JavaScript string context. It does not neutralize the HTML parser-sensitive sequence </script> inside the generated script element. Mitigation base64-encodes the cookie value to disallow escaping using cookie value.
