Description
ArcadeDB before 26.10.2 contains an improper authorization vulnerability that allows revoked users to retain access through already-open Postgres, Bolt, MongoDB, or Redis wire-protocol connections. Attackers holding an existing connection can keep reading and writing data after deletion, grant removal, or password rotation, because executors keep a stale ServerSecurityUser.
