CVE-2026-91010: Invisible Anti-Spam lets subscribers permanently delete stored submissions

Invisible Anti-Spam & CAPTCHA from 2.0.5 up to but not including 5.1.1, any logged-in user, including a Subscriber, can invoke the message-deletion AJAX operation without a capability check. The handler checks only that a nonce parameter exists rather than validating its value. This permits permanent deletion of every stored form submission. The export does not name the action, nonce field or deletion selector.
