CVE-2026-96538Network attack vectorHinoki check available

Database-role code execution via unrestricted file functions

Published Sep 28, 2026 · Updated Sep 28, 2026

Missing authorization in EnterpriseDB WarehousePG 7.x before 7.6.0-WHPG allows remote authenticated users to alter server files via SQL. The built-in pg_file_write, pg_file_rename, pg_file_unlink, and pg_logdir_ls functions allow ordinary roles to manipulate files or list logs without the intended privilege checks. A non-superuser can append commands to postgresql.auto.conf and obtain code execution as the postgres operating system user after a restart or configuration reload.
