+Subject: [PATCH] url: fix connection reuse for starttls protocols
+
+When a connection is tested for reuse in a transfer that *may* upgrade
+to TLS (commonly via STARTTLS), the SSL configuration must match the
+existing connection.
+
+Also reject non-TLS connections when the transfer requires TLS via
+STARTTLS (use_ssl >= CURLUSESSL_CONTROL).
+
+Adapted from upstream commit a86efdd7ca5433de9231e650f18247de8319ad16
+for the ConnectionExists() function in curl 7.61.1.
+
+Upstream-commit: a86efdd7ca5433de9231e650f18247de8319ad16
+Resolves: CVE-2026-8286
