Type confusion with PostgreSQL "internal" data type arguments allows any user to execute arbitrary code as the operating system user running the database, via calls to functions with that argument type. Type "internal" represents a class of mutually-incompatible data structures not intended for access from SQL. The system intended to prevent such function calls, but this prevention had gaps. Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected.

PostgreSQL before 9.0.19, 9.1.x before 9.1.15, 9.2.x before 9.2.10, 9.3.x before 9.3.6, and 9.4.x before 9.4.1 does not properly handle errors while reading a protocol message, which allows remote attackers to conduct SQL injection attacks via crafted binary data in a parameter and causing an error, which triggers the loss of synchronization and part of the protocol message to be treated as a new message, as demonstrated by causing a timeout or query cancellation.
