What is CVE-2026-85289?
CVE-2026-85289 is a medium-severity vulnerability in InvoicePlane, published on 25 Sep 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
InvoicePlane is a self-hosted open source application for managing invoices, clients, and payments. Prior to 1.7.2, InvoicePlane omits ensure_valid_post_request() from delete methods including Payments::delete(), Recurring::delete(), and User_clients::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.
