Axios: Prototype Pollution Gadget in axios toFormData Options

Summary Axios form serialization reads visitor, maxDepth, dots, indexes, metaTokens, and Blob from an internal options object without own-property guards. When Object.prototype has been polluted elsewhere in the same process, those inherited values can change how axios serializes multipart and...

CVE-2026-101909

The Axios promise-based HTTP client (versions 0.28.0 to 0.34.0 and 1.15.1 to 1.20.0 ) contains a Prototype Pollution Gadget in the toFormData options. The vulnerability exists because ToFormData processes inherited serialization options and visitor properties. This allows an attacker who has alre...

Node.js Module axios 0.31.1 < 0.33.0 / 1.15.1 < 1.18.0 DoS (CVE-2026-67321)

The version of the axios Node.js module installed on the remote host is 0.31.1 prior to 0.33.0 or 1.15.1 prior to 1.18.0. It is, therefore, affected by a vulnerability: - An incomplete depth-limit bypass in toFormData.js when serializing objects with top-level keys ending in ''. Attackers who...

CVE-2026-67321 axios 0.31.1 before 0.33.0 and 1.15.1 before 1.18.0 Denial of Service via maxDepth bypass

axios versions 0.31.1 before 0.33.0 and 1.15.1 before 1.18.0 contain an incomplete depth-limit bypass in toFormData.js when serializing objects with top-level keys ending in ''. Attackers who control object keys and nested values passed to axios form or parameter serialization can trigger a...

Uncontrolled Recursion

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 defaultVisitor function of lib/helpers/toFormData.js, which calls JSON.stringify on a value when its top-level key ends in , before the...

axios: Node.js: Axios: Denial of Service via unbounded recursion in toFormData with deeply nested request data

A flaw was found in Axios, a promise-based HTTP client for browsers and Node.js. This vulnerability occurs because the toFormData function recursively processes nested objects without a depth limit. A remote attacker can exploit this by sending deeply nested request data, which causes the Node.js...

SUSE CVE-2026-42039

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...
