Description

Versions of the package jsonpath before 1.3.0 are vulnerable to Arbitrary Code Injection via unsafe evaluation of user-supplied JSON Path expressions. The library relies on the static-eval module to process JSON Path input, which is not designed to handle untrusted data safely. An attacker can exploit this vulnerability by supplying a malicious JSON Path expression that, when evaluated, executes arbitrary JavaScript code, leading to Remote Code Execution in Node.js environments or Cross-site Scripting (XSS) in browser contexts. This affects all methods that evaluate JSON Paths against objects, including .query, .nodes, .paths, .value, .parent, and .apply.

• CWE-94Improper Control of Generation of CodeThe product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.
