I'm guessing the right answer is this:

diff --git a/gitweb/gitweb.perl b/gitweb/gitweb.perl
index 10ed9e5..a51a8ba 100755
--- a/gitweb/gitweb.perl
+++ b/gitweb/gitweb.perl
@@ -8055,6 +8055,7 @@ sub git_feed {
 		$feed_type = 'history';
 	}
 	$title .= " $feed_type";
+	$title = esc_html($title);
 	my $descr = git_get_project_description($project);
 	if (defined $descr) {
 		$descr = esc_html($descr);

but I did not test it (and I am not that familiar with gitweb, so it is
a slight guess from spending 5 minutes grepping and reading).
