Executive brief
Krayin laravel-crm is an open-source CRM platform for managing customer relationships and sales pipelines. An authenticated attacker with limited permissions can download email attachments belonging to other users by manipulating object identifiers, bypassing authorization checks. This allows unauthorized access to potentially sensitive business documents and communications.
Technical details
The vulnerability is an insecure direct object reference (IDOR) in the attachment-download endpoint caused by missing object-level authorization checks. An authenticated user can directly access the Storage::download function with an arbitrary attachment ID, with the ACL middleware unable to properly validate permissions due to an AJAX header bypass and missing authorization mapping. The vulnerability affects versions up to 2.2.5 and is fixed in version 2.2.6.
