Technical details

The vulnerability stems from missing authorization checks in the CRM Notification API endpoints. The mark_as_read() function accepts an arbitrary user parameter and applies modifications without validating the requester's permission to access that user's notifications. Authenticated attackers can query frappe.client endpoints with filters on to_user or invoke mark_as_read with another user's name to read, modify, or delete their notification records.

Affected products
