Summary

The ProSolution WP Client WordPress plugin before 2.0.9 does not sanitise a cookie value before using it in SQL queries, and processes that cookie on every request without any authentication or capability check, allowing unauthenticated users to read arbitrary data from the database and to delete the records the ProSolution WP Client WordPress plugin before 2.0.9 stores.
