HIGH Ad Inserter CVE published 2026-09-27

CVE-2026-81655

The Ad Inserter WordPress plugin before 2.8.19 does not correctly restrict access to one of its settings pages, making it reachable by every logged in user under a configuration its own settings allow, and does not filter the content saved there, allowing users with a role as low as subscriber to store code which is then executed as PHP or served unescaped to site visitors.
