CVE-2026-105281
HighCVSS 7.5Summary
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.
Risk Assessment
An attacker can obtain detailed information about the system's infrastructure and topology, potentially facilitating further attacks. This impacts confidentiality of the openPDC system data.

Configure authentication for the internal data publisher in openPDC or restrict network access to this interface. Verify that the default configuration is not used in production.
Other vulnerabilities in openPDC
See all- CVE-2026-85479Medium
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-2026-101022Medium
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-2026-105278Critical
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.
