CVE-2026-19385 is a heap-based buffer overflow in PostgreSQL pg_dump when processing an excessively long function transform list. A database object creator can craft a transform list that triggers the overflow when pg_dump processes the affected object, enabling code execution in the operating-system context of the user running pg_dump. PostgreSQL releases before 18.6, 17.11, 16.15, 15.19, and 14.24 are affected.
