NewCVE-2026-67312 (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 Allocation of Resources Without Limits or Throttling in the buildPath() function of lib/helpers/formDataToJSON.js, which recurses over bracket-delimited FormData key segments without a depth limit. An attacker can crash the Node.js process by supplying a FormData field name with tens of thousands of nested bracket segments, such as a[x][x][x]..., which exhausts the JavaScript call stack with a RangeError. Exploitation requires the application to pass attacker-controlled FormData into formDataToJSON, either by calling axios.formToJSON() on it or by sending it through axios with a JSON content type.
