Use after free in the PostgreSQL dblink extension allows an object creator to execute arbitrary code as the operating system user running the database, via type conversion code that re-enters dblink and closes a connection whose results an outer dblink call is reading. Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.
