- Critical 9.1
CVE-2026-39353
InvoicePlane is a self-hosted open source application for managing invoices, clients, and payments. Prior to 1.7.2-rc-1, InvoicePlane builds its permitted template list by scanning a PHP template directory that can be written through an administrator-controlled file-write capability. A malicious PHP file placed in the directory is automatically trusted by Mdl_templates and can be selected as public_invoice_template. When a public invoice is rendered, the guest View controller includes the trusted file and executes it with web-server privileges. This issue is fixed in version 1.7.2-rc-1.
