CVE-2026-89300: Unknown Wp Verify API

Medium severity, CVSS 5.3. EPSS: 0.2% chance of exploitation in the next 30 days.

The WP Verify API WordPress plugin through 1.0.0 does not have any authorisation check in one of its REST routes, allowing unauthenticated users to insert arbitrary data into its own database table, as well as to make the site send templated verification emails to arbitrary email addresses. The route is not rate limited either.

Affected products

• Unknown Wp Verify API: up to and including 1.0.0
