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
The Contest Gallery WordPress plugin before version 30.0.7 contains a missing authorization vulnerability (CWE-862) in one of its post-deletion handlers. Instead of verifying per-object capabilities or using nonce checks, it gates deletion functionality solely by a broad role-membership check. As a result, users with Author-level or higher roles can delete arbitrary content, including posts and pages they do not own, leading to potential integrity and availability impacts on site content.
Potential Impact
An attacker with Author-level or higher privileges can exploit this vulnerability to permanently delete arbitrary posts, pages, and other content they do not own. This can lead to loss of important site content and disruption of website operations. There is no indication of confidentiality impact. The vulnerability requires authenticated access with elevated privileges.
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 and higher user permissions carefully and monitor for unauthorized content deletions. Avoid granting Author-level privileges to untrusted users.
