CVE-2026-44496 Axios: Regular Expression Denial of Service (ReDoS) via Cookie Name Injection

Axios is a promise based HTTP client for the browser and Node.js. Axios versions before 0.32.0 on the 0.x line and before 1.16.0 on the 1.x line build a regular expression from the configured XSRF cookie name without escaping regex metacharacters. In standard browser environments, an attacker who...

CVE-2026-44489

Axios is a promise based HTTP client for the browser and Node.js. From 1.15.2 to before 1.16.0, nested objects created by utils.merge e.g., config.proxy are still constructed as plain with Object.prototype in their chain.

CVE-2026-44489

Axios version range 1.15.2–1.15.x is vulnerable to a header injection via the Proxy-Authorization header. The root cause is that nested objects created by utils.merge() (e.g., config.proxy) retain plain {} with Object.prototype in their chain, and setProxy() in lib/adapters/http.js (lines ~209–22...

CVE-2026-44492

Axios is a promise based HTTP client for the browser and Node.js. Prior to 0.32.0 and 1.16.0, Axios does not normalise IPv4-mapped IPv6 addresses. When NOPROXY lists an IPv4 address such as 127.0.0.1 or 169.254.169.254, a request URL using the IPv4-mapped IPv6 form ::ffff:7f00:1, ::ffff:a9fe:a9fe...

CVE-2026-44492

CVE-2026-44492 affects Axios where IPv4-mapped IPv6 addresses were not normalised before versions 0.32.0 and 1.16.0, causing NO_PROXY bypass for addresses like 127.0.0.1 or 169.254.169.254 and allowing proxy routing to reach internal services. The connected documents confirm the issue and state i...
