CVE-2026-100730— Grid Protection Alliance openPDC and openHistorian Deserialization of Untrusted Data

Quick assessment

Affected
Grid Protection Alliance openPDC
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.

在 openPDC 和 openHistorian 中，服务控制台接口会反序列化由客户端提供的数据结构。在使用 Windows 身份验证的系统上，攻击者必须已通过身份认证才能访问此功能；而在未启用 Windows 身份验证的系统上，未经身份验证的远程网络攻击者也可直接访问该功能。这使攻击者能够触发任意对象图的反序列化，从而可能导致以受影响服务账户的权限执行远程代码。

Vulnerability Title
Grid Protection Alliance openPDC and openHistorian Deserialization of Untrusted Data
Source: CVE Program / CVE List V5
Vulnerability Description
A service console interface on openPDC and openHistorian deserializes a client-supplied data structure. On systems using Windows Authentication, an attacker must already be authenticated to reach this function; on systems without Windows Authentication, this is reachable by an unauthenticated network attacker. This allows an attacker to trigger deserialization of an arbitrary object graph, which could allow remote code execution under the privileges of the affected service account.
