CVE-2026-89300
MediumCVSS 5.3Summary
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.
Risk Assessment
An unauthenticated attacker can pollute the database with arbitrary data, potentially leading to data integrity loss, and also abuse the server to send unsolicited emails (spam), which can harm domain reputation.
Recommendation
Update the WP Verify API plugin to the latest patched version or disable the REST route if not in use. Additionally, consider implementing rate limiting.
