CVE-2026-33639 Details
Description
InvoicePlane is a self-hosted open source application for managing invoices, clients, and payments. Prior to 1.7.2, InvoicePlane interpolates the administrator-controlled tax_rate_decimal_places setting into an ALTER TABLE statement for ip_tax_rates in Settings::index() without strict integer validation. A crafted setting value can add clauses to the schema-changing statement and remove or alter required database columns. The resulting schema corruption can permanently modify financial data structures and make the application unavailable. This vulnerability is fixed in 1.7.2.
A high-severity SQL injection vulnerability has been identified in InvoicePlane versions prior to 1.7.2. This vulnerability allows authenticated administrators to execute arbitrary Data Definition Language (DDL) commands, leading to database schema corruption and permanent financial data loss. The issue arises because the 'tax_rate_decimal_places' setting is interpolated into an ALTER TABLE statement without proper integer validation. Exploitation can be achieved by submitting a crafted value that manipulates the SQL query execution.
Users can update to InvoicePlane version 1.7.2 or later, where this vulnerability has been fixed.
