🚨High - Squid HTTP Request Smuggling via bare Transfer-Encoding: identity (CVE-2026-61642) Squid’s HTTP/1.1 parser improperly accepts the prohibited header form "Transfer-Encoding: identity", enabling request smuggling when a trusted client sends conflicting framing to desync Squid vs upstream. This can bypass intermediary security controls and poison upstream HTTP caches to serve attacker content at arbitrary URLs. 👉Affected: squid 3.3.0.1 < 7.6 | Upgrade to 7.6
Post summary
The text announces CVE-2026-61642 as a high-severity Squid HTTP request smuggling vulnerability via the 'Transfer-Encoding: identity' header, identifies affected versions, and recommends upgrading to Squid 7.6 as the remediation.
