Upgrade github.com/free5gc/udm to Latest secure release
github.com/free5gc/openapi fixed: 1.2.2 
Upgrade github.com/free5gc/openapi to 1.2.2
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 github.com/free5gc/udm

How to Check if You Are Affected

To determine whether your application is affected by CVE-2025-60633, inspect your project dependencies for Github.com/free5gc/udm:

inspect dependencies for github.com/free5gc/udm

Analyze the terminal output to locate any version of Github.com/free5gc/udm in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.2.2), your application is affected.

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