The function is named gp_add_master_standby() in WHPG 6, and WHPG 7 keeps that name as an alias. Unlike the other segment add and remove functions, it does not require superuser privileges. A low-privileged user who can open a utility-mode connection can use it to add a fake standby coordinator entry to gp_segment_configuration on a cluster that has no standby configured. Administrators then cannot add a real standby until a superuser removes the fake entry. User data is not exposed or modified.\n\n## Affected\n\n- `WarehousePG >= 6.27.1 < 6.27.7`\n- `WarehousePG >= 7.2.1 < 7.6.1`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":13,"depthScoreParts":{"impact":12.6,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
