Summary

psqlODBC versions before 18.00.0006 are affected. SQLSpecialColumns splices the table and schema names it receives into its catalog query without escaping them, unlike the other catalog functions (CWE-89). An application that passes an untrusted table or schema name to this function lets the caller run arbitrary SQL with the privileges of the connection.
