CVE-2026-111438 research
A source-linked research view connecting vulnerability evidence, reviewed campaign mentions, retained reporting and security tool listings.
Evidence summary
在 openGauss-server 的 src/common/backend/libpq/hba.cpp 中，复制连接认证存在访问控制绕过。hba_getauthmethod() 在处理 HADR/SW 复制发送方时，不要求 is_node_internal_connection()，直接调用 check_hba_replication()。check_hba_replication() 仅按 replication 标记做弱匹配，缺少普通 check_hba() 中的远程 trust 禁止等完整校验。因此，非内部网络的 HADR/SW 复制连接可绕过内部连接限制和完整 pg_hba 策略完成认证，进而通过复制协议读取备份与日志数据。 此问题随 HADR 复制发送方绕过内部连接校验进入代码，自 3.0.0 起即存在。受影响版本包括 3.0.x、3.1.x、5.0.x、5.1.0、6.0.x，以及 7.0.0-RC1、7.0.0-RC2、7.0.0-RC3。该问题已在 7.0.0-LTS版本修复，通过要求 HADR/SW 复制发送方必须经过 is_node_internal_connection 校验，使外部复制连接改走普通 check_hba() 并触发禁止远程 trust 策略。修复pr见https://gitcode.com/opengauss/openGauss-server/pull/9757。
