+# A QML Text element with no textFormat uses Text.AutoText. Qt then runs
+# mightBeRichText() over the string and promotes it to Text.RichText when it
+# looks like markup, and RichText fetches <img src="http://..."> through
+# QQuickPixmap. Any string that reaches such an element from outside the shell
+# — a notification summary, an MPRIS track title, a window title, an SSID, a
+# Bluetooth device name, clipboard content, a weather API response — can
+# therefore make the shell issue an unauthenticated outbound GET with no user
+# interaction.
+#
+# The promotion needs only that the attacker contribute the first `<` in the
+# string, on the first line. A fixed label in front of the value does not
+# protect it, and neither does .toUpperCase(), because the parser lowercases
+# the tag before looking it up.
+#
+# So require an explicit textFormat on every Text whose text: binding is not a
+# bare string literal. A literal carries no external data, so AutoText has
+# nothing to promote; this test is what catches the edit that later turns such
+# a literal into an expression.
