CVE-2026-50547

InvoicePlane is a self-hosted open source application for managing invoices, clients, and payments. Prior to 1.7.2, InvoicePlane's Invoices::generate_xml() method appends a database-derived xml_id to the XMLconfigs helper directory and includes the resulting PHP path without validating the identifier. A low-privileged attacker who can influence the e-invoice configuration can use traversal sequences to include an existing PHP file. The standalone advisory establishes local file inclusion; code execution requires a separate file-upload or file-write primitive. This issue is fixed in version 1.7.2.
