The advisory
WarehousePG (WHPG) 6.27.1 through 6.27.6 and 7.2.1 through 7.6.0 are affected by a missing authorization vulnerability (CWE-862) in the built-in cluster expansion functions gp_expand_lock_catalog() and gp_expand_bump_version(). Any authenticated database role can run them, and neither checks privileges. A low-privileged user can call gp_expand_lock_catalog() inside an open transaction to block all catalog changes across the cluster for every user, superusers included, until that transaction ends, which in practice requires a superuser to terminate the session. Blocked changes include DDL, temporary table creation, GRANT and CREATE ROLE. The same user can call gp_expand_bump_version() repeatedly. Each call disconnects sessions that hold temporary tables, with a FATAL error on their next catalog change, and makes every other session rebuild its segment connections.
Check your whole app
Dependencies are only half of it. Free and read-only: before you push, run npx shippable-dev scan localhost:3000 in your project folder, no account needed. For your live app, you prove it's yours with a one-line tag first.
