What is CVE-2026-16057?

The Contest Gallery plugin for WordPress contains a vulnerability in its post-deletion mechanism, where it fails to execute proper per-object capability and nonce checks. Instead, it relies on a coarse role-membership test, which allows any user with Author-level permissions or higher to delete posts, pages, and other content that they do not own. This security oversight can lead to unauthorized content removals and potential data loss for affected WordPress sites.

Affected Version(s)

Contest Gallery 0 < 30.0.7

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
