CVE-2026-124665 in Order Tracking Plugin
Summary
by MITRE • 11/12/2026
The Order Tracking WordPress plugin before 3.6.2 does not verify that a visitor owns the customer or sales representative account whose orders they request, and the account numbers default to sequential values, allowing unauthenticated users to retrieve the order history of every customer and sales representative, including order contact email addresses in some versions.

The vulnerability identified in Order Tracking WordPress plugin versions prior to 3.6.2 represents a critical failure in access control mechanisms, specifically categorized under CWE-284 Improper Access Control. The core technical flaw lies in the application's inability to validate whether an incoming request originates from an authorized user associated with the specific data being accessed. Instead of implementing robust session-based authentication checks or verifying ownership tokens for each API endpoint or page load that retrieves order information, the plugin relies on predictable and sequential account identifiers. This architectural weakness allows unauthenticated actors to iterate through these sequential values, effectively bypassing any intended security boundaries without needing valid credentials.
From a technical perspective, the exploitation of this vulnerability is straightforward due to the deterministic nature of the user ID generation process. Because customer and sales representative accounts are assigned numbers in a predictable sequence, an attacker can programmatically enumerate existing account IDs by incrementally requesting order data for consecutive identifiers. The server processes these requests without verifying that the requester has any legitimate relationship with the target account. This lack of object-level authorization means that the application treats every request as valid regardless of the user's actual permissions or identity status, leading to a complete breakdown in confidentiality controls.
The operational impact of this vulnerability is severe, resulting in widespread unauthorized disclosure of sensitive personal and business information. Attackers can retrieve comprehensive order histories for all customers and sales representatives on the platform. This includes not only transactional details but also personally identifiable information such as contact email addresses associated with those orders. The exposure of customer data violates privacy regulations like GDPR or CCPA depending on jurisdiction, while the leakage of sales representative accounts compromises internal business operations and potentially exposes proprietary pricing or client relationship strategies to competitors or malicious actors.
This incident aligns closely with MITRE ATT&CK technique T1078 Valid Accounts, as it involves gaining access to system resources through valid but improperly secured identifiers, even if those credentials are not explicitly stolen in the traditional sense of password theft. It also reflects CWE-640 Weak Password Recovery Mechanisms for Administrators when considering how easily account structures can be mapped and exploited due to poor identifier management practices inherent in many legacy WordPress plugins.
To mitigate this vulnerability, immediate action is required by upgrading the Order Tracking plugin to version 3.6.2 or later where these access control checks have been implemented. In addition to updating software, administrators should review their user account structures to ensure that future identifiers are not sequential and predictable, ideally utilizing random UUIDs or non-sequential database keys. Implementing strict server-side validation for all data retrieval endpoints is essential to prevent similar issues in other plugins. Regular security audits focusing on authorization logic rather than just authentication can help identify such gaps before they lead to significant data breaches.
