CVE-2026-16057: CWE-862 Missing Authorization in Contest Gallery
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.
AI Analysis
Technical Summary
CVE-2026-16057 is a missing authorization vulnerability (CWE-862) in the Contest Gallery WordPress plugin prior to version 30.0.7. The plugin's post-deletion handler does not enforce fine-grained permission checks, relying solely on a broad role-membership test. Consequently, users with Author-level or higher roles can delete arbitrary content they do not own, bypassing intended access controls. No CVSS score or official remediation guidance is currently available.
Potential Impact
Any user with Author-level or higher privileges can permanently delete arbitrary posts, pages, and other content they do not own. This could lead to unauthorized content removal and potential disruption of website content integrity.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict Author-level or higher user permissions where possible to limit exposure.
