CVE-2026-24946 identifies a missing authorization vulnerability in the Print Invoice & Delivery Notes plugin for WooCommerce, developed by tychesoftwares. This plugin is used to generate and manage invoices and delivery notes within WooCommerce-based e-commerce websites. The vulnerability arises from improperly configured access control mechanisms, allowing unauthorized users to bypass authorization checks. This can lead to unauthorized viewing, downloading, or manipulation of invoice and delivery note data, which often contains sensitive customer and order information. The affected versions include all versions up to and including 5.8.0. The vulnerability was reserved in late January 2026 and published in February 2026, with no CVSS score assigned yet and no known exploits reported in the wild. The lack of proper authorization checks suggests that attackers with network access to the WooCommerce site could exploit this flaw without needing user interaction or authentication, depending on the site’s configuration. Given the nature of the data involved, exploitation could lead to data leakage, privacy violations, and potential fraud. The plugin is widely used in WooCommerce installations, which powers a significant portion of global e-commerce websites, increasing the scope of potential impact. No official patches or mitigation links were provided at the time of publication, indicating that users must rely on vendor updates or implement access restrictions manually. The vulnerability highlights the importance of secure access control implementation in e-commerce plugins handling financial documents.

The impact of CVE-2026-24946 is significant for organizations running WooCommerce stores with the affected Print Invoice & Delivery Notes plugin. Unauthorized access to invoice and delivery note data can lead to exposure of sensitive customer information, including names, addresses, order details, and potentially payment information. This can result in privacy breaches, regulatory compliance violations (such as GDPR), and reputational damage. Attackers could use the information for targeted fraud, identity theft, or social engineering attacks. Additionally, manipulation of invoice data could disrupt order fulfillment processes or enable financial fraud. Since WooCommerce is widely adopted by small to medium-sized businesses globally, the vulnerability could affect a large number of e-commerce sites, especially those that have not updated or secured their plugins. The absence of known exploits in the wild reduces immediate risk but does not eliminate the threat, as attackers may develop exploits once the vulnerability details are public. The ease of exploitation, given missing authorization checks, increases the likelihood of attack attempts. Overall, the vulnerability poses a high risk to confidentiality and integrity of e-commerce transactional data.

To mitigate CVE-2026-24946, organizations should take the following specific actions: 1) Immediately check for and apply any official patches or updates released by tychesoftwares for the Print Invoice & Delivery Notes plugin. 2) If patches are not yet available, restrict access to the plugin’s endpoints by implementing web application firewall (WAF) rules or server-level access controls limiting access to trusted IP addresses or authenticated users only. 3) Review and harden WooCommerce and WordPress user roles and permissions to ensure only authorized personnel can access invoice and delivery note functionalities. 4) Monitor web server and application logs for unusual access patterns or attempts to access invoice-related URLs without proper authorization. 5) Consider temporarily disabling the plugin if it is not critical to operations until a secure version is available. 6) Educate staff about the risk and encourage vigilance for phishing or social engineering attempts that could leverage leaked invoice data. 7) Conduct a security audit of other WooCommerce plugins to identify similar access control weaknesses. 8) Implement network segmentation and least privilege principles to reduce the attack surface. These measures go beyond generic advice by focusing on immediate access restrictions and proactive monitoring tailored to the plugin’s functionality.
