Description OSIDB Bzimport 2026-11-12 14:33:27 UTC 
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.
