CVE-2026-85292

InvoicePlane: Loose Type Comparison in Core Authentication Check (Defense-in-Depth)

4.8 Medium

InvoicePlane is a self-hosted open source application for managing invoices, clients, and payments. Prior to 1.7.2, InvoicePlane's User_Controller compares the session user_type value with the required role by using PHP's loose inequality operator. Under a non-standard session backend that returns unexpected scalar types, type juggling can cause a value that is not strictly the required role to pass the authorization check. This can permit authentication or authorization bypass in affected session configurations. This issue is fixed in version 1.7.2.
