CVE-2026-1615 jsonpath CVE debrief

Who should care

Developers and administrators using the jsonpath package in Node.js environments or browser contexts should be aware of this vulnerability. They should assess their exposure and take steps to mitigate the risk, especially if they are using versions before 1.3.0.

Technical summary

The jsonpath package 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. This leads to Remote Code Execution in Node.js environments or Cross-site Scripting (XSS) in browser contexts. The vulnerability affects all methods that evaluate JSON Paths against objects.

Defensive priority

High priority should be given to updating the jsonpath package to version 1.3.0 or later. Developers should also review their code to ensure that user-supplied JSON Path expressions are properly sanitized and validated.

Recommended defensive actions

• Update the jsonpath package to version 1.3.0 or later.
• Review code to ensure user-supplied JSON Path expressions are properly sanitized and validated.
• Implement additional security measures, such as input validation and output encoding, to prevent exploitation.
• Monitor for suspicious activity and implement logging and auditing to detect potential attacks.
• Consider using alternative JSON Path libraries that are designed to handle untrusted data safely.
