CVE-2026-85274: InvoicePlane CSRF bypass in recurring invoice stop

CVE-2026-85274 · Severity: medium · CVSS 6.5 · Published 2026-09-25

InvoicePlane is a self-hosted invoicing application that manages recurring billing for customers. Prior to version 1.7.2, an authenticated administrator can be tricked into stopping recurring invoices through a simple image tag or link on an attacker-controlled website, causing legitimate recurring charges to halt without authorization. This disrupts recurring billing and can result in lost revenue.

Technical details

The vulnerability is a CSRF (Cross-Site Request Forgery) flaw in the Recurring::stop() method, which was accessible via HTTP GET requests without CSRF token validation. An attacker can craft a malicious webpage that triggers the stop action when visited by an authenticated admin, using techniques like an <img> tag. The fix adds POST-only enforcement and proper CSRF token validation to prevent unauthenticated state changes.
