PostgreSQL pg_dump not-null constraint name allows SQL injection

Assigner: PostgreSQL
Reserved: 26.10.2026 Published: 12.11.2026 Updated: 12.11.2026

SQL injection in PostgreSQL pg_dump allows an object creator to execute arbitrary SQL as the user restoring the dump, via an inherited column having a child-local not-null constraint whose name requires quoting. Within major version 18, minor versions before PostgreSQL 18.7 are affected. Versions before PostgreSQL 18 are unaffected.
