Summary

ArcadeDB before 26.10.2 contains an improper authorization flaw that lets revoked users keep access through already-open Postgres, Bolt, MongoDB, or Redis wire-protocol connections. Because executors keep a stale ServerSecurityUser, an attacker holding an existing connection can keep reading and writing data after deletion, grant removal, or password rotation. The flaw is classified as CWE-613 (Insufficient Session Expiration). Exploitation requires low privileges and a connection that was open before the revocation, and it can affect confidentiality and integrity.
