CVE-2026-49850 · Severity: high · CVSS 7.5 · Published 2026-09-25

InvoicePlane is a self-hosted application for managing invoices, clients, and payments. Prior to version 1.7.2, the application failed to protect invoice and tax deletion operations against cross-site request forgery (CSRF) attacks. An authenticated administrator could be tricked into deleting invoices or tax records by visiting attacker-controlled web content, resulting in the loss of financial data without the administrator's knowledge.

## Technical details

The Invoices::delete() and Invoices::delete_invoice_tax() routes accept state-changing operations without requiring POST requests or validating CSRF tokens, allowing an attacker to forge cross-origin delete requests. The vulnerability requires the target to be an authenticated administrator and relies on the administrator visiting attacker-controlled content, but no additional user interaction is needed. Version 1.7.2 hardens these endpoints with CSRF token validation.
