NewCVE-2026-101901 (opens in a new tab)How to fix?
Upgrade axios to version 1.20.0 or higher.
Overview
axios is a promise-based HTTP client for the browser and Node.js.
Affected versions of this package are vulnerable to Improper Validation of Specified Quantity in Input via unsafe runtime option handling in the fetch and HTTP adapters, where user-supplied fetchOptions are merged into the resolved request options without sanitization or allowlist enforcement. An attacker who can influence request configuration can supply option values that override Axios-owned fields (such as signal, method, headers, or body) or inject unexpected fetch option keys, causing the request pipeline to crash and producing a denial of service.
