CVE-2026-83550— Postgres-exporter: net/http/pprof exposed on metrics listener

Quick assessment

Affected
Red Hat Multicluster Global Hub
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.

Postgres-exporter 中存在一个安全漏洞。由于盲目导入了 包，调试端点暴露在未经验证的指标监听器上。集群网络内的远程攻击者可以访问这些端点。这可能导致信息泄露，潜在地暴露进程参数、完整的 goroutine 堆栈，以及从堆转储中提取的敏感数据（如数据库连接字符串或密码）。此外，通过反复进行 CPU 分析可能导致拒绝服务（DoS）攻击。

Vulnerability Title
Postgres-exporter: net/http/pprof exposed on metrics listener
Source: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in postgres-exporter. Due to the blank import of `net/http/pprof`, debug endpoints are exposed on the unauthenticated metrics listener. A remote attacker within the cluster network can access these endpoints. This allows for information disclosure, potentially revealing process arguments, full goroutine stacks, and sensitive data like database connection strings or passwords from heap dumps. Additionally, repeated CPU profiling through these endpoints can lead to a denial of service.
