Technical details
A response discrepancy vulnerability (CWE-203/CWE-204) exists in the password reset endpoint of FreeScout prior to version 1.8.219. When a reset request is submitted, the application returns a success message with a specific CSS class for valid emails, while returning an error message and a different CSS class for invalid emails. Because there is no rate limiting on this endpoint, an unauthenticated attacker can perform automated network-based enumeration to harvest valid agent email addresses. This vulnerability serves as a prerequisite for targeted phishing or further impersonation attacks. The issue is resolved in version 1.8.219 by normalizing the response.
