+Subject: [PATCH] HTTP/1.1: Transfer-Encoding:identity is prohibited (#2427)
+
+HTTP specification deprecated identity encoding but still allows
+its use as an unknown encoding when the Transfer-Encoding
+header is otherwise correctly used.
+
+Squid compliance update at the time kept accepting identity
+encoding as it was being used by agents. The form supported was
+Transfer-Encoding:identity.
+
+However, the HTTP specification explicitly requires that any
+encoding MUST be wrapped within chunked encoding.
+
+As such the bare Transfer-Encoding:identity form Squid accepted
+is explicitly prohibited.
+
+The correct Transfer-Encoding:identity,chunked syntax has been
+rejected by Squid for nearly 5 years already without complaint.
+So support is being dropped entirely here.
+
+CVE: CVE-2026-61642
+Upstream-Status: Backport [https://github.com/squid-cache/squid/commit/d06f48de8b8cc9a378cb91ecfe8e89b6e81696d2]
