CVE-2026-42041

Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.1 and 0.31.1, the Axios library is vulnerable to a Prototype Pollution "Gadget" attack that allows any Object.prototype pollution to silently suppress all HTTP error responses 401, 403, 500, etc., causing them to be...

CVE-2026-42036

Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.1 and 0.31.1, when responseType: 'stream' is used, Axios returns the response stream without enforcing maxContentLength. This bypasses configured response-size limits and allows unbounded downstream consumption. This...

CVE-2026-42035

Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.1 and 0.31.1, a prototype pollution gadget exists in the Axios HTTP adapter lib/adapters/http.js that allows an attacker to inject arbitrary HTTP headers into outgoing requests. The vulnerability exploits duck-type...

CVE-2026-42040

Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.1 and 0.31.1, the encode function in lib/helpers/AxiosURLSearchParams.js contains a character mapping charMap at line 21 that reverses the safe percent-encoding of null bytes. After encodeURIComponent'\x00' correctly...

CVE-2026-42042

Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.1 and 0.31.1, the Axios library's XSRF token protection logic uses JavaScript truthy/falsy semantics instead of strict boolean comparison for the withXSRFToken config property. When this property is set to any truthy...

CVE-2026-42034 Axios: HTTP adapter streamed uploads bypass maxBodyLength when maxRedirects: 0

Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.1 and 0.31.1, for stream request bodies, maxBodyLength is bypassed when maxRedirects is set to 0 native http/https transport path. Oversized streamed uploads are sent fully even when the caller sets strict body limits...

CVE-2026-42034

CVE-2026-42034 affects Axios, a promise-based HTTP client for browser and Node.js. The vulnerability occurs in the HTTP adapter for stream request bodies: for versions prior to 1.15.1 and 0.31.1, maxBodyLength is bypassed when maxRedirects is set to 0 on the native http/https transport path, caus...

CVE-2026-42037

Axios is a promise based HTTP client for the browser and Node.js. From 1.0.0 to before 1.15.1, the FormDataPart constructor in lib/helpers/formDataToStream.js interpolates value.type directly into the Content-Type header of each multipart part without sanitizing CRLF \r\n sequences. An attacker w...

CVE-2026-42037

Axios 1.0.0–1.15.0/1.15.0x suffer a CRLF injection in the FormDataPart constructor (lib/helpers/formDataToStream.js) where value.type is interpolated into multipart part Content-Type headers without CRLF sanitization. An attacker controlling the .type of a Blob/File-like object can inject arbitra...

CVE-2026-42038 Axios: no_proxy bypass via IP alias allows SSRF

Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.1 and 0.31.1, he fix for noproxy hostname normalization bypass is incomplete. When noproxy=localhost is set, requests to 127.0.0.1 and ::1 still route through the proxy instead of bypassing it. The shouldBypassProxy...

CVE-2026-42043

Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.1 and 0.31.1, an attacker who can influence the target URL of an Axios request can use any address in the 127.0.0.0/8 range other than 127.0.0.1 to completely bypass the NOPROXY protection. This vulnerability is due t...

CVE-2026-42043

Axios: CVE-2026-42043 affects Axios versions prior to 1.15.1 and 0.31.1, where an attacker controlling the request URL could bypass NO_PROXY by using loopback 127.0.0.0/8 addresses (except 127.0.0.1). Root cause is an incomplete fix for CVE-2025-62718. Impact is potential exposure via proxy/SSRF ...
