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

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

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.
