+Date: Thu, 3 Aug 2023 12:24:13 -0700
+Subject: [PATCH] [release-branch.go1.20] html/template: support HTML-like
+ comments in script contexts
+
+Per Appendix B.1.1 of the ECMAScript specification, support HTML-like
+comments in script contexts. Also per section 12.5, support hashbang
+comments. This brings our parsing in-line with how browsers treat these
+comment types.
+
+Thanks to Takeshi Kaneko (GMO Cybersecurity by Ierae, Inc.) for
+reporting this issue.
+
+Fixes #62196
+Fixes #62395
+Fixes CVE-2023-39318
