CVE-2026-28163Network attack vectorHinoki check available

Unauthenticated user-approval actions

Published Aug 20, 2026 · Updated Aug 20, 2026

Broken access control in WPExperts New User Approve before 3.2.9 allows remote attackers to perform unauthorized actions via unspecified vectors. Patchstack has not published the affected endpoint, handler, or missing check, and the WordPress.org changelog for 3.2.9 says only that it fixed a code improvement. Exposure is limited to sites running the plugin and reachable over the network; the published CVSS limits the proven impact to integrity, with no cited evidence of data disclosure or service interruption.
