Summary

The New User Approve plugin for WordPress in all versions up to and including 3.0.9 is vulnerable to unauthorized data disclosure due to insufficient API key validation using loose equality comparison. This allows unauthenticated attackers to retrieve personally identifiable information (PII), including usernames and email addresses, via the Zapier REST API endpoints by exploiting PHP type juggling with the api_key parameter set to "0" on sites where the Zapier API key has not been configured.

Risk Assessment

Breach of user PII confidentiality could lead to GDPR violations and loss of trust.

Recommendation

Update the New User Approve plugin to the latest version (above 3.0.9) or remove it if not in use.
