What is CVE-2026-85292?
CVE-2026-85292 is a medium-severity authentication bypass vulnerability in InvoicePlane, published on 25 Sep 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
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.
