Critical Authentication Bypass Flaw Found in SureCart Plugin Versions Up to 4.9.5

The National Vulnerability Database has published a record for CVE-2026-112241, identifying a critical security vulnerability within the SureCart plugin developed by Brainstorm Force. This flaw allows for authentication abuse through spoofing techniques, potentially compromising user accounts and system integrity. The advisory highlights the severity of the issue for organizations relying on this e-commerce solution.

According to the NVD record, the vulnerability is rated with a CVSS score of 9.8, which places it in the critical severity category. This high score indicates that the flaw is a significant security concern. The weakness is classified under CWE-290, specifically noting authentication bypass by spoofing as the underlying technical failure.

Context and Background

The technical classification of this issue points to a failure in how the application verifies user identity. Authentication bypass by spoofing occurs when an attacker can manipulate requests to appear as if they originate from a trusted source or user. This allows unauthorized access without valid credentials, undermining the core security controls of the application.

The National Vulnerability Database serves as the U.S. government’s repository of standards-based vulnerability management data. By assigning a CVSS score of 9.8, the NVD signals that this is a high-priority issue for security teams. The use of CWE-290 helps developers and researchers understand the specific nature of the logic error that permits this unauthorized access.

Who Is Affected

The vulnerability impacts Brainstorm Force SureCart software across a wide range of versions. According to the NVD description, the issue affects SureCart from n/a through version 4.9.5. This means that any installation running these versions is potentially vulnerable to authentication abuse.

Users have not been informed of a confirmed patch or fix for this specific vulnerability in the provided source material. Security teams should assume that all installations up to version 4.9.5 are at risk until a verified update is released by the vendor. The broad version range suggests that many existing deployments may currently be exposed.

What should you do?

Security professionals should immediately audit their environments to identify any instances of SureCart running versions 4.9.5 or earlier. Monitoring for unusual authentication activity can help detect potential exploitation attempts before significant damage occurs. Organizations should prepare for a vendor update while implementing compensating controls to reduce exposure.
