Use after free in PostgreSQL pg_show_all_settings() allows a database user to retrieve memory contents, via loading a module while the function is scanning custom-variable placeholders that the module replaces and frees. Within major versions 16-18, minor versions before PostgreSQL 18.7, 17.12, and 16.16 are affected. Versions before PostgreSQL 16 are unaffected.
