CVE-2026-101904

Axios is a promise-based HTTP client for the browser and Node.js. From 1.0.0 until 1.20.0, the dispatchRequest function normalizes inherited Object.prototype.headers from a replacement request configuration. A separate same-process prototype-pollution flaw sets Object.prototype.headers, and trust...

CVE-2026-101903 Axios: ReDoS in fromDataURI data: URL parser freezes the Node event loop (DoS)

Axios is a promise-based HTTP client for the browser and Node.js. From 1.16.1 until 1.20.0, the RFC 2397 regular expression allows slash characters on both sides of the media-type separator. An application passes an attacker-controlled malformed data URL containing many slash characters and no...

CVE-2026-101902 Axios: Prototype-Pollution Gadget in the Default Instance Allows Inherited Object.prototype.method to Override HTTP Method

Axios is a promise-based HTTP client for the browser and Node.js. From 0.27.2 until 0.34.0 and 1.20.0, Axios default-instance requests that omit an explicit method can read an inherited method value from Object.prototype. If another vulnerability in the same process pollutes...

CVE-2026-101894

The decompress package for Node.js extracts archives. Prior to 10.2.2 and 11.1.4, the default decompressinput, output API relies on lexical containment checks that do not account for the kernel following a planted symlink chain. An attacker can supply a crafted archive containing chained symlink...

CVE-2026-101901

The Axios HTTP client (versions 1.13.0 through 1.20.0 ) is vulnerable to a Denial of Service (DoS) because Http2Sessions lacks adequate error handling during ClientHttp2Session initialization or reuse. When a request uses httpVersion: 2 and the session emits an error, the error escapes standard P...

CVE-2026-101901 Axios: Denial of Service via Unhandled 'error' Event in HTTP/2 ClientHttp2Session Initialization

Axios is a promise-based HTTP client for the browser and Node.js. From 1.13.0 until 1.20.0, Http2Sessions does not install adequate error handling for a ClientHttp2Session during Axios HTTP/2 session initialization or reuse. A request uses httpVersion: 2 and the ClientHttp2Session emits an error...

CVE-2026-101900 Axios: Fetch Adapter Header Injection via Inherited FormData getHeaders

Axios is a promise-based HTTP client for the browser and Node.js. From 1.12.0 until 1.20.0, ResolveConfig reads inherited Symbol.toStringTag, append, and getHeaders properties while resolving FormData headers. A separate same-process prototype-pollution flaw supplies an array or non-plain class...

CVE-2026-101900

The Axios HTTP client (versions 1.12.0 to 1.20.0 ) is vulnerable to a Fetch Adapter Header Injection flaw. The issue occurs because ResolveConfig reads inherited properties—specifically Symbol.toStringTag, append, and getHeaders—while resolving FormData headers. This can be exploited via a separa...
