CVE-2026-42039

HIGH

Axios: unbounded recursion in toFormData causes DoS via deeply nested request data

Title source: cna
STIX 2.1

Description

Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.1 and 0.31.1, toFormData recursively walks nested objects with no depth limit, so a deeply nested value passed as request data crashes the Node.js process with a RangeError. This vulnerability is fixed in 1.15.1 and 0.31.1.
