+Subject: [PATCH 1/2] [Backport] html/template: support HTML-like comments in
+ script contexts
+
+Reference: https://open.codehub.huawei.com/OpenSourceCenter/golang/go/merge_requests/89
+Conflict: NA
+
+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.
+
+Note: The upstream does not submit this change to go1.17 according to the rules of MinorReleases.
+Corego3.x are based on go1.17.8. Therefore, it need to submit the change to corego3.x.

+Subject: [PATCH 2/2] [Backport] html/template: properly handle special tags
+ within the script context
+
+Reference: https://open.codehub.huawei.com/OpenSourceCenter/golang/go/merge_requests/94
+Conflict: NA
+
+The HTML specification has incredibly complex rules for how to handle
+"<!--", "<script", and "</script" when they appear within literals in
+the script context. Rather than attempting to apply these restrictions
+(which require a significantly more complex state machine) we apply
+the workaround suggested in section 4.12.1.3 of the HTML specification [1].
+
+More precisely, when "<!--", "<script", and "</script" appear within
+literals (strings and regular expressions, ignoring comments since we
+already elide their content) we replace the "<" with "\x3C". This avoids
+the unintuitive behavior that using these tags within literals can cause,
+by simply preventing the rendered content from triggering it. This may
+break some correct usages of these tags, but on balance is more likely
+to prevent XSS attacks where users are unknowingly either closing or not
+closing the script blocks where they think they are.
+
+Thanks to Takeshi Kaneko (GMO Cybersecurity by Ierae, Inc.) for
+reporting this issue.
+
+Note: The upstream does not submit this change to go1.17 according to the rules of MinorReleases.
+Corego3.x are based on go1.17.8. Therefore, it need to submit the change to corego3.x.
