This vulnerability has a CVSS 3.1 base score of 7.3, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

This affects the package total.js before 3.4.7. The set function can be used to set a value into the object according to the path. However the keys of the path being set are not properly sanitized, leading to a prototype pollution vulnerability. The impact depends on the application. In some cases it is possible to achieve Denial of service (DoS), Remote Code Execution or Property Injection.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
