CVE-2026-104629

HighCVSS 8.8

Published: 09/10/2026(UTC)Updated: 09/10/2026(UTC)Translated: 09/10/2026(UTC)NVD NIST

Summary

A component loading mechanism in openPDC and openHistorian will construct and run any specified type, which may be an invalid component to load. An attacker with an authenticated user account and the ability to place a file on the host filesystem can use this to run arbitrary constructor code, and this code runs with the privileges of the affected service account.

Risk Assessment

An authenticated attacker can execute arbitrary code with the privileges of the service account, leading to full compromise of the service and potential escalation on the host.

Recommendation

Update openPDC and openHistorian to a patched version and restrict filesystem write access on the host to trusted accounts.

Other vulnerabilities in openPDC/openHistorian

CVE-2026-100730Critical
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.
