CVE-2026-85479
MediumCVSS 5.3Summary
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.
Risk Assessment
Lack of authentication allows unauthorized entities to access data and potentially modify it, which could lead to data integrity breaches or system disruption. This is a serious risk in production environments.
Recommendation
Configure authentication for the STTP interface in openPDC. Restrict network access to this interface to trusted sources only.
Other vulnerabilities in openPDC
See all- CVE-2026-105281High
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-2026-101022Medium
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.
