Overview

CVE-2026-19350 is a missing authorization vulnerability found in the TakePOS module of Dolibarr ERP, a popular open-source enterprise resource planning (ERP) system. This vulnerability affects versions up to 23.0.3 and allows remote attackers to perform unauthorized actions, potentially leading to data breaches or system compromise.

Understanding the Vulnerability / Threat

Root Cause Analysis

The root cause of this vulnerability is a missing authorization check in the `fail` function of the `htdocs/takepos/invoice.php` file. This function is part of the TakePOS module, which is a critical component of the Dolibarr ERP system. The vulnerability is classified as CWE-862 (Missing Authorization) and CWE-863 (Authorization Bypass Through User-Controlled Data).

Attack Surface & Vector

The attack surface of this vulnerability is the network-exposed interface of the Dolibarr ERP system, specifically the TakePOS module. An attacker can exploit this vulnerability remotely, without requiring any prior authentication or privileges. The attack vector is through the network, with a low attack complexity and no user interaction required.

Exploitation Mechanics — Scenario Walkthrough

Scenario: Compromising a Corporate Dolibarr ERP Instance

  1. Initial Position: An attacker gains access to the network and discovers a Dolibarr ERP instance running version 23.0.3.
  2. Triggering the Flaw: The attacker crafts a malicious request to the `htdocs/takepos/invoice.php` file, specifically targeting the `fail` function. The request is designed to bypass authorization checks and perform an unauthorized action.
  3. What Breaks: The authorization check in the `fail` function fails, allowing the attacker to perform the unauthorized action. This could lead to data breaches, system compromise, or other malicious activities.
  4. Attacker's Prize: The attacker gains unauthorized access to sensitive data or system functionality, potentially leading to lateral movement, data exfiltration, or other malicious activities.

Real-World Impact

The real-world impact of this vulnerability is significant, as it allows remote attackers to perform unauthorized actions on the Dolibarr ERP system. This could lead to data breaches, system compromise, or other malicious activities. The affected user base is significant, as Dolibarr ERP is a popular open-source ERP system used by many organizations worldwide.

Detection & Defense

Immediate Mitigations

To mitigate this vulnerability, administrators should apply the patch 8992ce8704da947b6abe7b65a6fe59aed736bb81 to their Dolibarr ERP instance. This patch fixes the missing authorization check in the `fail` function of the `htdocs/takepos/invoice.php` file.

Detection Strategies

Defenders can detect exploitation attempts by monitoring network traffic and system logs for suspicious activity. Specifically, they can look for requests to the `htdocs/takepos/invoice.php` file with unusual or malicious parameters.

Long-Term Hardening
