--- Comment #4 from Krinkle <[email protected]> ---
Quoted from commit message:

> cascading, users could who cannot normally protect pages could
> "protect" them by transcluding them on protected pages they are
> allowed to edit.

Please elaborate on this, especially with regards to the following part of the
change:

@@     function buildCleanupScript() {
-        global $wgRestrictionLevels, $wgOut;
+        global $wgRestrictionLevels, $wgCascadingRestrictionLevels, $wgOut;
-
-        $cascadeableLevels = array();
-        foreach ( $wgRestrictionLevels as $key ) {
-            if ( User::groupHasPermission( $key, 'protect' )
-                || $key == 'protect'
-            ) {
-                $cascadeableLevels[] = $key;
-            }
-        }
+
+        $cascadeableLevels = $wgCascadingRestrictionLevels;

It now no longer verifies that the values in cascadeable levels are names of
user groups that have the "protect" right. Doesn't that cause a situation
exactly like the one you appear to be trying to prevent?

Also, from looking at the code, contrary to the commit message it is not
hardcoded to 'sysop'. On the contrary, it is dynamically constructed based on
wgRestrictionLevels and filtered to only include groups that have the 'protect'
right. If I'm reading the use case explained in this bug and in the commit
message correctly, it seems that this is already possible without this change.


Re-opening with 1.22 milestone to prevent forgetting about this before release.
Feel free to re-close.
