CVE-2026-89300: CWE-862 Missing Authorization in WP Verify API
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.
AI Analysis
Technical Summary
CVE-2026-89300 identifies a missing authorization check (CWE-862) in the WP Verify API WordPress plugin versions up to 1.0.0. The vulnerability resides in a REST API route that does not verify the identity or permissions of the requester. As a result, unauthenticated attackers can insert arbitrary data into the plugin's database table and cause the site to send verification emails to arbitrary recipients. The absence of rate limiting on this route further exacerbates the risk of abuse.
Potential Impact
Unauthenticated attackers can manipulate the plugin's database by inserting arbitrary data, potentially impacting data integrity. They can also abuse the email functionality to send verification emails to arbitrary addresses, which could be leveraged for spam or phishing campaigns. The lack of rate limiting increases the likelihood of automated abuse. However, there is no indication of remote code execution or direct site takeover from this vulnerability.
Mitigation Recommendations
No official patch or fix is currently documented. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, it is recommended to disable or restrict access to the vulnerable REST API route if possible, or remove the WP Verify API plugin if it is not essential.
