psqlODBC SQL injection through SQLSpecialColumns table and schema names

Summary

SQLSpecialColumns in psqlODBC splices the table and schema names it receives into its catalog query without escaping them, while the other catalog functions escape them. An application that passes an untrusted table or schema name to SQLSpecialColumns lets the caller execute arbitrary SQL with the privileges of the connection. Versions before psqlODBC 18.00.0006 are affected.

Remediation

1. Inventory every PostgreSQL psqlODBC deployment, including staging.
2. Upgrade PostgreSQL psqlODBC to 18.00.0006.
3. Confirm the running version after the upgrade.
