Greptile Overview

Greptile Summary

This PR fixes an RBAC issue for native users accessing the license endpoint by adding a special case in the authentication validator. When a user is not found in the current organization but the request path is license, the code now checks if the user belongs to at least one organization using org_users::list_orgs_by_user(). If the user is part of any organization, the request is allowed with minimal User role permissions.

Key Changes

• Added import for db::org_users module
• Introduced special handling for the license endpoint path in validate_credentials()
• Prevents native users from getting stuck in logout loops when accessing pages that call the license API

Issues Found

• Minor typo in comment: "go t any" should be "go to any" (line 207)

Confidence Score: 4/5

• This PR is safe to merge with minimal risk as it addresses a specific bug in authentication handling
• The fix is targeted and solves a legitimate issue where native users get stuck in logout loops. The change adds a safety check that ensures users belong to at least one organization before granting access to the license endpoint. The implementation uses existing, tested database functions and follows the pattern of returning a minimal role. The only concern is that this creates a special case in the authentication flow, but it's well-documented with clear comments explaining the rationale.
• No files require special attention - the single file change is straightforward with only a minor typo to fix
