NewCVE-2026-67313 (opens in a new tab)How to fix?
Upgrade axios to version 0.33.0, 1.18.0 or higher.
Overview
axios is a promise-based HTTP client for the browser and Node.js.
Affected versions of this package are vulnerable to Uncontrolled Recursion in the buildPath() function of lib/helpers/formDataToJSON.js, which recurses once per FormData key path segment without enforcing a maximum depth. An attacker can crash the process by supplying a FormData field name with thousands of nested bracket segments, such as a[x][x][x]..., which drives formDataToJSON() into recursion that exhausts the JavaScript call stack with a RangeError. Exploitation requires the application to process untrusted FormData through formToJSON() or by sending it with a JSON content type.
