Background
jsreport is an npm package that provides a platform for generating reports using JavaScript. It allows users to create and customize reports using various templates and data sources. However, versions 2.5.0 and earlier of jsreport are vulnerable to an unintended require and server-side request forgery (SSRF) attack. This vulnerability can be exploited by attackers to execute arbitrary code.
Vulnerability Detail
The vulnerability in jsreport arises from the unintended require and SSRF vulnerabilities. The unintended require vulnerability allows an attacker to include functionality from an untrusted control sphere, potentially leading to the execution of arbitrary code. The SSRF vulnerability enables an attacker to make requests to internal resources or external systems, bypassing any restrictions that may be in place. This can result in unauthorized access to sensitive information or the execution of malicious actions.
How To Fix
Minimum fixed version
2.6.0
This is the first release that contains the fix.

Workaround
If updating jsreport is not immediately feasible, a temporary workaround is to implement proper input validation and sanitization. This can help prevent the exploitation of the SSRF vulnerability by blocking malicious requests to internal or external resources. Additionally, it is crucial to review and restrict the permissions of the application to minimize the potential impact of an unintended require attack.
Conclusion
The vulnerability in jsreport version 2.5.0 and earlier poses a significant risk as it allows for server-side request forgery and the inclusion of functionality from an untrusted control sphere. To mitigate this vulnerability, it is crucial to update jsreport to version 2.6.0 or later. Additionally, implementing input validation and sanitization can serve as a temporary workaround.
