Description

The Yo WordPress plugin from 1.1 through 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, allowing unauthenticated attackers to perform SQL injection and read arbitrary database contents including administrator password hashes.

Affected WordPress components

A confirmed match is backed by the plugin or theme slug. A possible match is based on the product name only and should be verified.

Affected products and versions

  • Unknown Yo — From 1.1 (including) to 1.3.1 (including)
