What fixes it

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

The Pro Like Button WordPress plugin before 2.0 does not properly sanitize and escape a parameter before using it in a SQL query, allowing unauthenticated users to perform SQL injection attacks.
