EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2% (5th percentile of EPSS-scored CVEs). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
