CVE-2026-105278
Critical · 9.8
CWE-798 Oct 9, 2026
Grid Protection Alliance openPDC (Docker image) Use of Hard-coded Credentials
The published Docker image for openPDC includes a fixed administrative credential with no forced change on first use. An attacker with network access to the management interface can authenticate using this credential and gain full administrative control of the application.
CVE-2026-85479
Medium · 5.3
CWE-306 Oct 9, 2026
Grid Protection Alliance openPDC and openHistorian Missing Authentication for Critical Function
The STTP-based data publisher on openPDC accepts network connections without authentication in its default configuration. An unauthenticated network attacker can connect to this interface and exchange data with it.
CVE-2026-105281
High · 7.5
CWE-306 Oct 9, 2026
Grid Protection Alliance openPDC and openHistorian Missing Authentication for Critical Function
The internal data publisher on openPDC accepts network connections without authentication in its default configuration. An unauthenticated network attacker can connect to this interface and retrieve the complete device and measurement topology of the system.
CVE-2026-104629
High · 8.8
CWE-470 Oct 9, 2026
Grid Protection Alliance openPDC and openHistorian Use of Externally-Controlled Input to Select Classes or Code
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.
CVE-2026-101022
Medium · 4.3
CWE-918 Oct 9, 2026
Grid Protection Alliance openPDC and openHistorian Server-Side Request Forgery (SSRF)
A Modbus connection feature on openPDC accepts a caller-specified destination address and port with no restriction on which internal hosts may be targeted. An authenticated user can attempt connections to arbitrary internal network destinations, revealing which destinations are reachable. With repeated attempts, an attacker may be able to map the internal network.
CVE-2026-100730
Critical · 9.8
CWE-502 Oct 9, 2026
Grid Protection Alliance openPDC and openHistorian Deserialization of Untrusted Data
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.
