It means an admin has not reviewed it for suitability yet. Most wikis don't patrol edits.

Patrolling only has practical use when an army of admins is simultaneously reviewing edits that occur so fast that it can be a challenge for any single one of them to keep up. For anything smaller than Wikipedia, it usually just doesn't matter.
