Bagisto is an open source laravel eCommerce platform. A stored Cross-Site Scripting (XSS) vulnerability exists in Bagisto prior to version 2.3.10 within the CMS page editor. Although the platform normally attempts to sanitize `<script>` tags, the filtering can be bypassed by manipulating the raw HTTP POST request before submission. As a result, arbitrary JavaScript can be stored in the CMS content and executed whenever the page is viewed or edited. This exposes administrators to a high-severity risk, including complete account takeover, backend hijacking, and malicious script execution. Version 2.3.10 fixes the issue.
The CVSS score for this vulnerability is 5.2, indicating a medium severity level. Organizations using affected versions should be aware of the potential impacts, as the vulnerability allows attackers to execute arbitrary scripts in the context of users who access the compromised CMS pages.
Risk to organizations includes the potential for unauthorized access to sensitive administrative functions and the ability to manipulate user data through malicious scripts. Organizations should prioritize patching immediately.
Currently, no known exploits have been confirmed publicly for this vulnerability, and it is not included in the Known Exploited Vulnerabilities (KEV) catalog. This should not diminish the urgency for organizations to address the vulnerability in their systems.
Organizations should schedule remediation of this vulnerability as part of their regular security practices. Ensuring that Bagisto is updated to version 2.3.10 or later is crucial in mitigating the risks associated with this vulnerability.
Vulnerability Details
The vulnerability is classified as a stored Cross-Site Scripting (XSS) flaw under CWE-79. It affects versions of Bagisto prior to 2.3.10. The vulnerability allows an attacker, with high privileges, to execute arbitrary JavaScript code that could lead to serious security breaches. This includes the potential for account takeover and unauthorized access to backend functions.
The CVE was published on January 2, 2026, and has been analyzed thoroughly. The severity score based on CVSS 3.1 is 8.4, indicating it as a high-severity vulnerability, emphasizing the critical nature of the risk involved.
Technical Analysis
The root cause of the vulnerability lies in the inadequate filtering of input provided by users through the CMS page editor. The platform attempts to sanitize `<script>` tags but fails to enforce strict validation rules, allowing attackers to bypass these measures through crafted HTTP POST requests. As a result, attackers can inject malicious scripts into the CMS content.
The attack vector is network-based, as it requires access to the Bagisto application over the internet. The complexity of the attack is considered low, as it does not require any specific conditions or extensive technical skills. High privileges are required to exploit this vulnerability, specifically access to the CMS editor.
User interaction is not required for the exploitation of this vulnerability once the malicious content is injected into the CMS. The impacts include high confidentiality and integrity risks due to the potential for unauthorized data manipulation and exposure. Availability is not directly impacted.
Risk & Impact Analysis
The real-world deployment risk associated with this vulnerability is significant. Organizations using Bagisto must consider the implications of a successful XSS exploit, which can lead to complete account takeover and potential backend control. The blast radius is extensive, as any administrator accessing the compromised content could be at risk.
Given the CVSS score of 8.4 and the potential for exploitation, organizations should address this vulnerability in their priority patch cycle. Ensuring that updates are applied promptly will mitigate the risks effectively.
