InvoicePlane is a self-hosted open source application for managing invoices, clients, and payments. In version 1.7.2, Users::form() performs no object-level authorization check on user_id = 1. A Secondary Administrator (user_type = 1, user_id != 1) can rewrite the Primary Administrator's user_type to 2 (Guest / read-only), destroying the root account's privilege and locking the legitimate owner out of the instance. At time of publication, there are no publicly available patches.

InvoicePlane is a self-hosted open source application for managing invoices, clients, and payments. In version 1.7.2, an authorization guard to Users::change_password(), was added to address a previous authorization flaw that allowed a secondary administrator (user_type=1, user_id != 1) to directly change the password of the primary administrator (user_id=1) through users/change_password/{id}. That remediation, however, protects only the direct password-change operation. It does not protect the identity attribute that password recovery actually trusts: user_email. Users::form() applies no equivalent object-level authorization check when editing the primary administrator's account, and user_email is not included in PROTECTED_FIELDS. A secondary administrator can therefore rewrite the primary administrator's email address, then drive the public password-recovery flow — which resolves the account by user_email — to receive the reset token and take over user_id=1. The result is an alternate attack path that achieves the same impact PR #1638 was intended to prevent: cross-administrator full account takeover of the primary administrator. This issue has been patched via commit 8616fa4.

InvoicePlane is a self-hosted open source application for managing invoices, clients, and payments. A Stored Cross-Site Scripting (XSS) vulnerability occurs in the Edit Quotes functions of InvoicePlane version 1.7.0. In the Editing Quotes function, the application does not validate user input at the quote_number parameter. Although administrator privileges are required to exploit it, this is still considered a critical vulnerability as it can cause actions such as unauthorized modification of application data, creation of persistent backdoors through stored malicious scripts, and full compromise of the application's integrity. Version 1.7.1 patches the issue.

InvoicePlane is a self-hosted open source application for managing invoices, clients, and payments. A Stored Cross-Site Scripting (XSS) vulnerability exists in InvoicePlane 1.7.0 via the Family Name field. The `family_name` value is rendered without HTML encoding inside the family dropdown on the product form. When an administrator creates a family with a malicious name, the payload executes in the browser of any administrator who visits the product form. Version 1.7.1 patches the issue.

InvoicePlane is a self-hosted open source application for managing invoices, clients, and payments. A Stored Cross-Site Scripting (XSS) vulnerability exists in InvoicePlane 1.7.0 via the Invoice Number field. An authenticated administrator can inject malicious JavaScript that executes when any administrator views the affected invoice or visits the dashboard. Version 1.7.1 patches the issue.

InvoicePlane is a self-hosted open source application for managing invoices, clients, and payments. A Stored Cross-Site Scripting (XSS) vulnerability occurs in the upload Invoice Logo functions of InvoicePlane version 1.7.0. The Upload Invoice Logo function allows the application to upload svg files. Although administrator privileges are required to exploit it, this is still considered a critical vulnerability as it can cause actions such as unauthorized modification of application data, creation of persistent backdoors through stored malicious scripts, and full compromise of the application's integrity. Version 1.7.1 patches the issue.

InvoicePlane is a self-hosted open source application for managing invoices, clients, and payments. A Stored Cross-Site Scripting (XSS) vulnerability exists in InvoicePlane 1.7.0 via the Product Unit Name fields. An authenticated administrator can inject malicious JavaScript that executes when any administrator views an invoice containing a product with the malicious unit. Version 1.7.1 patches the issue.

InvoicePlane is a self-hosted open source application for managing invoices, clients, and payments. A Stored Cross-Site Scripting (XSS) vulnerability exists in InvoicePlane (latest version) that allows an authenticated user with permissions to manage Invoice Groups to inject malicious JavaScript into the "Identifier Format" field. This script executes when any user views the invoice list or the main dashboard. Version 1.7.1 patches the issue.

InvoicePlane is a self-hosted open source application for managing invoices, clients, and payments. A stored cross-site scripting (XSS) vulnerability in the Sumex invoice view allows an authenticated user with client and invoice management privileges to execute arbitrary JavaScript in the browser of any user viewing the invoice. This can lead to session hijacking, data theft, or other malicious actions on behalf of the victim user. Version 1.7.1 patches the issue.

InvoicePlane is a self-hosted open source application for managing invoices, clients, and payments. A Stored Cross-Site Scripting (XSS) vulnerability occurs in the Edit Invoices functions of InvoicePlane version 1.7.0. When editing invoices, the application does not validate user input at the `invoice_number` parameter. Although administrator privileges are required to exploit it, this is still considered a critical vulnerability as it can cause actions such as unauthorized modification of application data, creation of persistent backdoors through stored malicious scripts, and full compromise of the application's integrity. Version 1.7.1 patches the issue.
