Summary

The Yo WordPress plugin from version 1.1 to 1.3.1 does not sanitize or parameterize the username request parameter before using it in a SQL query, and reads it before WordPress applies its request escaping. This allows unauthenticated attackers to perform SQL injection and read arbitrary database contents including administrator password hashes.

Risk Assessment

An attacker can gain full access to the database, including administrator password hashes, potentially leading to complete compromise of the WordPress site.

Recommendation

Update the Yo plugin to the latest patched version. If not available, temporarily disable the plugin and monitor logs for suspicious queries.
