Background
node-rules is an npm package that provides a rule engine for JavaScript applications. It allows users to define and execute rules based on JSON data. However, versions 3.0.0 and prior to 5.0.0 of node-rules are vulnerable to code injection. The 'fromJSON()' function in node-rules does not properly sanitize the 'rules' argument, allowing users to inject arbitrary commands.
Vulnerability Detail
The code injection vulnerability in node-rules can be exploited by attackers to execute arbitrary commands on the affected system. By manipulating the 'rules' argument of the 'fromJSON()' function, an attacker can inject malicious code that will be executed during rule execution. This can lead to various security risks, including unauthorized access, data breaches, and remote code execution.
How To Fix
Latest published version: 9.2.0 as of 23 Oct 2026
npm install node-rules@9.2.0Upgrading to it may include breaking changes; the version below is the minimum fixed release for this vulnerability.

Workaround
If upgrading to the latest version is not immediately feasible, a temporary workaround is to manually sanitize the 'rules' argument before passing it to the 'fromJSON()' function. This can be done by implementing input validation and filtering techniques to ensure that only trusted and safe JSON data is processed.
Conclusion
In conclusion, the code injection vulnerability in node-rules can be a serious security risk, allowing attackers to execute arbitrary commands. It is crucial to upgrade to the latest version of node-rules or implement proper input validation to mitigate this vulnerability.
