Summary
The Contest Gallery WordPress plugin before 30.0.7 does not perform per-object capability or nonce checks in one of its post-deletion handlers, gating it only by a coarse role-membership test, which allows any Author-level or higher user to permanently delete arbitrary posts, pages, and other content they do not own.
