How to Fix GHSA-4c29-gfrp-g6x9

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

CefSharp.Common fixed: 117.2.20 
Upgrade CefSharp.Common to 117.2.20
CefSharp.Common.NETCore fixed: 117.2.20 
Upgrade CefSharp.Common.NETCore to 117.2.20
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 CefSharp.Common

How to Check if You Are Affected

To determine whether your application is affected by GHSA-4c29-gfrp-g6x9, inspect your project dependencies for CefSharp.Common:

inspect dependencies for CefSharp.Common

Analyze the terminal output to locate any version of CefSharp.Common in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 117.2.20), your application is affected.

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