+From 9db0e74f606b8afb28cc71d4b1c8b4ed24cabbf5 Mon Sep 17 00:00:00 2001
+From: Roland Shoemaker <bracew...@google.com>
+Date: Thu, 13 Apr 2023 14:01:50 -0700
+Subject: [PATCH] [release-branch.go1.19] html/template: emit filterFailsafe
+ for empty unquoted attr value
+
+An unquoted action used as an attribute value can result in unsafe
+behavior if it is empty, as HTML normalization will result in unexpected
+attributes, and may allow attribute injection. If executing a template
+results in a empty unquoted attribute value, emit filterFailsafe
+instead.
+
+Thanks to Juho Nurminen of Mattermost for reporting this issue.
+
+For #59722
+Fixes #59815
+Fixes CVE-2023-29400
