How to Fix GHSA-7wwr-h8cm-9jf7

To remediate this vulnerability, upgrade all affected Duplicate Advisory dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

OPCFoundation.NetStandard.Opc.Ua fixed: 1.5.374.158 
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-7wwr-h8cm-9jf7, 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-305: Authentication Bypass by Primary Weakness, where the authentication algorithm is sound, but the implemented mechanism can be bypassed as the result of a separate weakness that is primary to the authentication error. 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## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-4rcc-7pg7-f57f. 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 using HTTPS endpoints.
