How to Fix GHSA-g636-q5fc-4pr7

To remediate this vulnerability, upgrade all affected accounts 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/moov-io/customers fixed: 0.5.0 
Upgrade github.com/moov-io/customers to 0.5.0
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/moov-io/customers

How to Check if You Are Affected

To determine whether your application is affected by GHSA-g636-q5fc-4pr7, inspect your project dependencies for accounts:

inspect dependencies for github.com/moov-io/customers

Analyze the terminal output to locate any version of accounts in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.5.0), 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 General Security Weakness. In accounts, 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

@alovak found that currently when we build hash of account number we do not "salt" it. Which makes it vulnerable to rainbow table attack. **What did you expect to see?** I expected salt (some random number from configuration) to be used in [hash.AccountNumber](https://github.com/moov-io/customers/blob/master/pkg/secrets/hash/account_number.go#L13) I would generate salt per tenant at least (maybe per organization).
