CVE-2026-14680 is a type-confusion vulnerability in PostgreSQL's protections for SQL calls to functions accepting the internal data type. The internal type represents mutually incompatible implementation-specific data structures that are not intended to be supplied through SQL. Gaps in the call-prevention logic allow a database user to invoke affected functions with internal arguments, confusing incompatible structures and achieving arbitrary code execution in the PostgreSQL server process. PostgreSQL versions before 18.6, 17.11, 16.15, 15.19, and 14.24 are affected.
