The advisory
The BSK PDF Manager WordPress plugin through 3.8.1 does not properly sanitise and escape a parameter before using it in a SQL statement, which could allow authenticated users with contributor-level access and above to perform SQL injection attacks and read sensitive data such as administrator password hashes from the database.
