## Technical details

The crm.api.doc.get_linked_docs_of_document endpoint fails to verify user permissions before returning linked documents. An authenticated attacker can bypass authorization by specifying the name of a lead, deal, comment, or user they lack read access to, allowing them to retrieve sensitive linked data such as call log phone numbers, organization details, and mention notification text.
