+Subject: [PATCH] web: Fix an open redirect in StaticFileHandler
+
+Under some configurations the default_filename redirect could be exploited
+to redirect to an attacker-controlled site. This change refuses to redirect
+to URLs that could be misinterpreted.
+
+A test case for the specific vulnerable configuration will follow after the
+patch has been available.
