Prior to 1.8.231, when limit_user_customer_visibility is enabled, the load_customer_info AJAX action performs a global lookup using an attacker-controlled customer email and checks only whether the agent can access a separately supplied mailbox. A non-admin agent can name an accessible mailbox and retrieve an unrelated customer's rendered profile without invoking CustomerPolicy::view(). The response can expose names, email addresses, phone numbers, company and job information, postal addresses, social profiles, websites, and confidential internal agent notes. This issue is fixed in version 1.8.231.\n\n## Affected\n\n- `freescout < 1.8.231`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":48,"depthScoreParts":{"impact":35.8,"likelihood":0.1,"exploitation":12,"ransomware":0},"changes":[]}
