CVE-2026-16057: Unknown Contest Gallery

Medium severity, CVSS 6.5. EPSS: 0.4% chance of exploitation in the next 30 days.

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.
