How to Fix GHSA-3839-6r69-m497

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.

github.com/Masterminds/goutils fixed: 1.1.1 
Upgrade github.com/Masterminds/goutils to 1.1.1
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/Masterminds/goutils

How to Check if You Are Affected

To determine whether your application is affected by GHSA-3839-6r69-m497, inspect your project dependencies for Duplicate Advisory:

inspect dependencies for github.com/Masterminds/goutils

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 1.1.1), 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-331: Insufficient Entropy, where the product uses an algorithm or scheme that produces insufficient entropy, leaving patterns or clusters of values that are more likely to occur than others. 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## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-xg2h-wx96-xgxr. This link is maintained to preserve external references. ## Original Description Randomly-generated alphanumeric strings contain significantly less entropy than expected. The `RandomAlphaNumeric` and `CryptoRandomAlphaNumeric` functions always return strings containing at least one digit from 0 to 9. This significantly reduces the amount of entropy in short strings generated by these functions.
