Upgrade OPCFoundation.NetStandard.Opc.Ua to 1.5.374.158
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for OPCFoundation.NetStandard.Opc.Ua

How to Check if You Are Affected

To determine whether your application is affected by GHSA-qv5f-57gw-vx3h, inspect your project dependencies for Duplicate Advisory:

inspect dependencies for OPCFoundation.NetStandard.Opc.Ua

Analyze the terminal output to locate any version of Duplicate Advisory in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.5.374.158), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-639: Authorization Bypass Through User-Controlled Key, where the system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data. In Duplicate Advisory, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-h958-fxgg-g7w3. This link is maintained to preserve external references. ## Original Description Vulnerability in the OPC UA .NET Standard Stack before 1.5.374.158 allows an unauthorized attacker to bypass application authentication when the deprecated Basic128Rsa15 security policy is enabled.
