All versions of EnterpriseDB Postgres Advanced Server (EPAS) from 15.0 prior to 15.7.0 and from 16.0 prior to 16.3.0 may allow users using edbldr to bypass role permissions from pg_read_server_files. This could allow low privilege users to read files to which they would not otherwise have access.
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
