How to Fix GHSA-6hcf-g6gr-hhcr

To remediate this vulnerability, upgrade all affected `openssl` `X509Extension dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

openssl fixed: 0.10.48 
Upgrade openssl to 0.10.48
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 openssl

How to Check if You Are Affected

To determine whether your application is affected by GHSA-6hcf-g6gr-hhcr, inspect your project dependencies for `openssl` `X509Extension:

inspect dependencies for openssl

Analyze the terminal output to locate any version of `openssl` `X509Extension in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.10.48), your application is affected.

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