CVE-2026-104949 · Severity: info · Published 2026-10-21

WarehousePG is a distributed database cluster management system. A low-privileged user can add a fake standby coordinator entry without proper authorization checks, preventing legitimate administrators from configuring a real standby until a superuser manually removes the fake entry. No user data is exposed or modified by this vulnerability.

## Technical details

The gp_add_coordinator_standby() function (and its gp_add_master_standby() alias in version 6) in WarehousePG fails to enforce superuser privilege requirements, unlike other segment add/remove functions. A low-privileged user with utility-mode connection access can invoke this function to insert false entries into gp_segment_configuration, causing a denial of service for legitimate standby configuration. The vulnerability requires local/utility-mode access and does not result in data exposure.
