CVE-2026-21447: High Vulnerability in Webkul Bagisto

CVE-2026-21447 is a high-severity vulnerability affecting Webkul's Bagisto, an open-source Laravel eCommerce platform. The vulnerability is classified as an Insecure Direct Object Reference, which allows authenticated users to manipulate the order ID parameter. This manipulation can lead to unauthorized access to sensitive purchase information from other customers' orders. The CVSS score for this vulnerability is 7.1, indicating a high risk to organizations.

Organizations using Bagisto need to be aware of the potential impact of this vulnerability. Attackers may leverage this weakness to gain access to sensitive data, leading to fraud and significant breaches of trust. The vulnerability has been patched in version 2.3.10, making immediate remediation crucial for organizations still running older versions.

As of now, there are no known public exploits or proof-of-concept code for this vulnerability, but given its nature, it may only be a matter of time before one emerges. Therefore, organizations should prioritize patching immediately to mitigate any potential risks.

The urgency for defenders is high, as the vulnerability allows for the exposure of sensitive data and potential fraud. Organizations must ensure they are running the latest version of Bagisto to protect against this vulnerability.

Vulnerability Details

The vulnerability is described as follows: Insecure Direct Object Reference in the customer order reorder function allows any authenticated customer to add items from another customer's order to their own shopping cart by manipulating the order ID parameter. This exposes sensitive purchase information and enables potential fraud. Version 2.3.10 patches the issue.

The CVSS vector for this vulnerability is CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N, with a base score of 7.1 and high severity. The attack vector is network-based, with low complexity and low privileges required for exploitation.

The vulnerability affects all versions of Bagisto prior to 2.3.10, as specified in the CPE details:

Technical Analysis

The root cause of this vulnerability is a failure to properly restrict access to sensitive resources based on user authentication and authorization. By manipulating the order ID parameter, authenticated users can gain access to other users' orders, which should not be permissible.

The attack vector is network-based, meaning that an attacker only needs to be authenticated to exploit this vulnerability. The attack complexity is low, as it does not require any special conditions or user interaction. The privileges required are low as well, allowing any authenticated customer to perform the attack.

In terms of confidentiality, the impact is high, as sensitive purchase data can be exposed. The integrity impact is low since an attacker cannot alter the existing orders but can view them. There is no availability impact.

Risk & Impact Analysis

Risk to organizations includes unauthorized access to sensitive customer information, which can lead to fraud and a breach of customer trust. The potential blast radius is significant, particularly for organizations that handle a large volume of transactions and personal data. The urgency for remediation is high, especially considering the CVSS score of 7.1.

Organizations should address this vulnerability in their priority patch cycle, as the potential for exploitation exists, and public knowledge of the vulnerability may increase the risk of attacks.

Exploitation Status

Affected Versions

This vulnerability affects all versions of Bagisto prior to 2.3.10. Organizations must ensure they have updated to this version or later to mitigate the risk associated with CVE-2026-21447.

Mitigation & Remediation

To remediate this vulnerability, organizations should immediately upgrade to Bagisto version 2.3.10 or later. If upgrading is not possible, consider implementing configuration hardening measures to restrict access to order functionalities and monitor for unauthorized access attempts.

For further security assessments, organizations can utilize services such as penetration testing to identify similar weaknesses.

Detection Guidance

Organizations should monitor logs for unusual activity related to order reordering functionalities. Behavioral anomalies such as high-frequency access to order data or changes in order IDs should be flagged for further investigation.

AppSecure Threat Intelligence Insight
