CVE-2025-14971 in Link Invoice Payment for WooCommerce Plugin
Summary
by MITRE • 01/27/2026
The Link Invoice Payment for WooCommerce plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the createPartialPayment and cancelPartialPayment functions in all versions up to, and including, 2.8.0. This makes it possible for unauthenticated attackers to create partial payments on any order or cancel any existing partial payment via ID enumeration.

The vulnerability identified as CVE-2025-14971 affects the Link Invoice Payment for WooCommerce plugin, a widely used payment processing extension for WordPress e-commerce sites. This security flaw resides in the plugin's handling of partial payment operations within the WooCommerce framework, specifically targeting versions up to and including 2.8.0. The issue manifests through insufficient access control mechanisms that fail to verify user permissions before executing critical payment functions, creating a significant security risk for online retailers relying on this plugin for their payment processing workflows.
The technical implementation of this vulnerability stems from the absence of proper capability checks within the createPartialPayment and cancelPartialPayment functions. These functions operate without requiring authentication verification or authorization validation, allowing any attacker to manipulate payment data through direct API requests. The flaw enables attackers to exploit ID enumeration techniques to identify valid order identifiers and subsequently perform unauthorized partial payment creation or cancellation operations. This represents a classic authorization bypass vulnerability where the system fails to validate whether the requesting entity has legitimate permissions to modify specific payment records.
The operational impact of this vulnerability extends beyond simple data integrity concerns, potentially enabling financial fraud and revenue loss for affected e-commerce platforms. Unauthenticated attackers can create fraudulent partial payments on any order within the system, effectively allowing them to manipulate payment statuses and potentially circumvent complete payment processing requirements. Additionally, the ability to cancel existing partial payments creates opportunities for attackers to disrupt legitimate payment workflows, potentially causing disputes between customers and merchants while undermining the trust in the payment processing system. This vulnerability directly violates the principle of least privilege and demonstrates inadequate input validation and access control implementation.
Organizations utilizing the affected plugin version should immediately implement mitigations including updating to the patched version of the Link Invoice Payment for WooCommerce plugin, which addresses the missing capability checks in the affected functions. System administrators should also consider implementing additional monitoring controls to detect unusual payment activity patterns that might indicate exploitation attempts. The vulnerability aligns with CWE-284 (Improper Access Control) and represents a clear violation of the ATT&CK technique T1078.004 (Valid Accounts: Cloud Accounts) when attackers leverage the lack of proper authorization controls to manipulate payment data. Organizations should also review their overall payment processing security posture and consider implementing additional security layers such as API rate limiting and enhanced logging of payment-related operations to prevent similar vulnerabilities in other components of their e-commerce infrastructure.
