CVE-2026-88003 Details
Description
InvoicePlane is a self-hosted open source application for managing invoices, clients, and payments. Prior to 1.7.2, InvoicePlane fails to revoke administrative privileges after a role downgrade because Admin_Controller trusts the user_type snapshot stored in an existing session instead of revalidating ip_users.user_type. When one administrator downgrades another account, the target's active session continues to authorize administrative requests. The downgraded user can use Users::form() to set user_type back to 1, restoring the database role and making the privilege escalation persistent. This vulnerability is fixed in 1.7.2.
A vulnerability in InvoicePlane prior to version 1.7.2 allows for persistent privilege escalation by failing to revoke administrative rights after a role downgrade. The issue arises because the Admin_Controller relies on a user_type value stored in the session, which does not reflect real-time changes made to the user's role in the database. As a result, a downgraded administrator can still perform administrative tasks and even restore their original privileges, creating a lasting escalation of rights.
Users are advised to upgrade to InvoicePlane version 1.7.2, which addresses this vulnerability by invalidating sessions immediately after a user's role is changed.
