CVE-2026-85289: InvoicePlane: Missing CSRF Token Validation on Multiple Delete Endpoints

Published Sep 25, 2026
·
Updated

InvoicePlane is a self-hosted open source application for managing invoices, clients, and payments. Prior to 1.7.2, InvoicePlane omits ensurevalidpostrequest() from delete methods including Payments::delete(), Recurring::delete(), and Userclients::delete(). Although the routes require POST, they do not validate the request's CSRF token. An attacker can submit a cross-origin form through an authenticated administrator's browser to delete financial records and other application data. This issue is fixed in version 1.7.2.

Frequently Asked Questions

1

Who is exposed to this issue?

Deployments running InvoicePlane versions earlier than 1.7.2 are affected. Exploitation targets an authenticated administrator through their browser.

2

What does an attacker need to exploit it?

The attacker does not need application credentials, but must cause an authenticated administrator to submit a cross-origin form. The vulnerable delete routes accept POST requests without validating a CSRF token.

3

Which actions can be triggered?

The affected delete methods include Payments::delete(), Recurring::delete(), and User_clients::delete(). Successful exploitation can delete financial records and other application data.

4

How can this be remediated?

Upgrade InvoicePlane to version 1.7.2, which adds the missing CSRF validation for the affected delete endpoints.
