This vulnerability allows server-side template injection in Webkul's Bagisto platform, which is an open-source Laravel eCommerce solution. The affected versions are all prior to 2.3.10. The vulnerability can be exploited by a low-privilege user through the first name and last name fields. As the CVSS score is 7.4, categorized as high severity, organizations using this software should prioritize patching immediately.
Risk to organizations includes unauthorized access to sensitive data, potential data corruption, and disruption of services. Given the ease of exploitation with a low privilege requirement, the urgency to remediate this vulnerability cannot be overstated.
Currently, there are no known public exploits or proof-of-concept attacks reported. However, the risk remains significant due to the nature of the vulnerability. Organizations should address this vulnerability in their immediate patch cycle.
The vulnerability was disclosed on January 2, 2026, and the fix was included in version 2.3.10. All users are encouraged to upgrade their installations without delay.
Vulnerability Details
The official description states that versions of Bagisto prior to 2.3.10 are vulnerable to server-side template injection. This vulnerability allows attackers to execute arbitrary code on the server by manipulating input fields that are improperly validated.
The CVSS score for this vulnerability is 7.4 (high severity), indicating a significant risk. The attack vector is network-based with low complexity, requiring low privileges and no user interaction, which enhances the risk profile.
The disclosure date was January 2, 2026, and the vulnerability is classified under CWE-1336, indicating an issue with improper input validation.
Technical Analysis
The root cause of this vulnerability stems from improper validation of user input. Attackers may leverage this flaw by injecting malicious templates through the first and last name fields, allowing them to execute arbitrary commands on the server.
The attack vector is network-based, meaning it can be exploited remotely. The complexity of the attack is low, and it requires only low privileges, which means that even non-administrative users can potentially exploit this vulnerability.
No user interaction is required for exploitation, increasing the likelihood of successful attacks. If exploited, the impacts on confidentiality, integrity, and availability are all high, as attackers may gain unauthorized access and control over the affected systems.
Risk & Impact Analysis
Organizations utilizing Bagisto should be particularly concerned about the potential for data breaches and service disruptions. If compromised, attackers could access sensitive information, modify or delete data, and impact the integrity of the application's functionality.
The blast radius of this vulnerability is considerable, given that it affects all versions prior to 2.3.10. Organizations should address this vulnerability in their priority patch cycle.
The urgency for remediation is heightened by the CVSS score indicating a high severity level. Organizations should act swiftly to patch their installations to prevent potential exploitation.
