This critical vulnerability poses a significant risk to any organization using InvoicePlane for invoice management, as it could lead to unauthorized access and control over the server. Organizations running affected versions should prioritize upgrading to the patched version to mitigate this risk.

Original NVD Description

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.
