This makes it possible for unauthenticated attackers to enumerate arbitrary customer records and disclose personally identifiable information -  including first name, last name, email address, and phone number - by iterating the customer[id] parameter. This issue is exploitable only when the site is configured with customer authentication disabled (guest checkout enabled).\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":24,"depthScoreParts":{"impact":23.7,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
