CVE-2026-104947

Quick assessment

Affected
EnterpriseDB WarehousePG
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

WarehousePG (WHPG) 7.2.1 至 7.6.0 版本受内置函数 中缺失授权（CWE-862）漏洞的影响。任何已认证的数据库角色均可在无需 GRANT 授权的情况下执行该函数，从而绕过 PostgreSQL 对底层 函数施加的超级用户限制。低权限用户可强制其他会话（包括超级用户会话）的 segment 后端将其内存上下文详情写入 segment 服务器日志；虽然攻击者无法直接读取这些日志，但其中可能包含其他用户缓存计划中的查询文本。此外，攻击者可重复调用该函数，以生成大量日志输出。Warehouse

Vulnerability Description
WarehousePG (WHPG) 7.2.1 through 7.6.0 is affected by a missing authorization vulnerability (CWE-862) in the built-in function gp_log_backend_memory_contexts(). Any authenticated database role can run this function without a GRANT. It also gets around the superuser restriction that PostgreSQL places on the underlying pg_log_backend_memory_contexts() function. A low-privileged user can force the segment backends of any other session, superuser sessions included, to write their memory context details to the segment server logs, which the attacker cannot read. Those details can include query text from other users' cached plans, and the call can be repeated to generate large amounts of log output. WarehousePG 6.x is not affected.
