Type confusion in PostgreSQL operator commutator and negator links allows an object creator to execute arbitrary code as the operating system user running the database, via linking operators having different result types or creating inconsistent reciprocal links. Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
