Summary
The ntharim dot-access package versions from 0.0.3 through 1.0.0 are affected. The get() function concatenates the supplied path into a new Function body, which is a code injection flaw (CWE-94). A remote attacker who supplies a crafted path can run JavaScript and operating system commands in the Node.js process, without privileges or user interaction.

Description from the CNA
dot-access 0.0.3 through 1.0.0 contains a code injection vulnerability that allows remote attackers to execute JavaScript by supplying crafted paths to get(). The path is concatenated into a new Function body in index.js, so attackers can reach constructor.constructor to load child_process and run operating system commands in the Node.js process.
