Prototype Pollution

Axios is vulnerable to Prototype Pollution. The vulnerability is due to Object.prototype.proxy being able to influence the Node HTTP adapter through an un-rehardened request configuration, allowing an attacker who can pollute the prototype to route requests through an attacker-controlled proxy...

GHSA-68JP-44VC-2X5H Duplicate Advisory: Axios Node HTTP adapter can use an inherited proxy after interceptor config cloning

Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-gcfj-64vw-6mp9. This link is maintained to preserve external references. Original Description axios in a Node.js deployment using the HTTP adapter can route requests through an attacker-controlled proxy. axios...

CVE-2026-67318

axios versions =1.13.0 Node.js HTTP adapter fail to enforce the configured maxBodyLength limit on streamed request bodies when requests are sent with httpVersion: 2. Because Node's HTTP/2 request API does not honor the maxBodyLength option and axios's byte-counting stream wrapper is gated on...

CVE-2026-67320 axios before 0.33.0 Prototype Pollution via Node HTTP adapter

axios in a Node.js deployment using the HTTP adapter can route requests through an attacker-controlled proxy. axios hardens merged request configuration by creating a null-prototype object, but request interceptors run after the merge; a common immutable interceptor pattern such as ...config or...

CVE-2026-67320

CVE-2026-67320 affects axios on Node.js when using the HTTP adapter. A hardened config object can be re-exposed to regular objects via common patterns, allowing an attacker to pollute Object.prototype.proxy and route plaintext-HTTP requests through a malicious proxy. Impact includes exposure of A...

Axios Node HTTP adapter can use an inherited proxy after interceptor config cloning

Summary Axios’ Node.js HTTP adapter can route requests through an attacker-controlled proxy when Object.prototype.proxy is polluted and request configuration is materialized as a regular object before dispatch. Recent axios releases harden merged request config by creating a null-prototype object...

Prototype Pollution

Overview axios is a promise-based HTTP client for the browser and Node.js. Affected versions of this package are vulnerable to Prototype Pollution in the Node HTTP adapter lib/adapters/http.js, which reads config.proxy through the prototype chain after a request interceptor returns a plain-object...

PT-2026-67300

Name of the Vulnerable Software and Affected Versions axios versions 0.31.1 through 0.32.x axios versions 1.15.2 through 1.17.x Description In Node.js deployments using the HTTP adapter, a bypass of prototype pollution hardening allows requests to be routed through an attacker-controlled proxy...

CVE-2025-58754

Axios is a promise based HTTP client for the browser and Node.js. When Axios starting in version 0.28.0 and prior to versions 0.30.2 and 1.12.0 runs on Node.js and is given a URL with the data: scheme, it does not perform HTTP. Instead, its Node http adapter decodes the entire payload into memory...
