Official Description

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.

Technical Analysis

CVE-2026-6019 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
