CVE-2026-42264 — Axios: Prototype pollution read-side gadgets in HTTP adapter allow credential injection and request hijacking

Affected: axios, Red Hat AMQ Broker 7.13.6, Red Hat AMQ Broker 7.14.1, Red Hat Data Grid 8.6.2, Red Hat Advanced Cluster Security 4.9, Red Hat Advanced Cluster Security for Kubernetes 4.10, Red Hat Advanced Cluster Security for Kubernetes 4.11, Red Hat Ansible Automation Platform 2.7, Red Hat Migration Toolkit 1.8, Red Hat Migration Toolkit for Applications 8.1 and 38 more

Axios is a promise based HTTP client for the browser and Node.js. From version 1.0.0 to before version 1.15.2, fFive config properties (auth, baseURL, socketPath, beforeRedirect, and insecureHTTPParser) in the HTTP adapter are read via direct property access without hasOwnProperty guards, making them exploitable as prototype pollution gadgets. When Object.prototype is polluted by another dependency in the same process, axios silently picks up these polluted values on every outbound HTTP request. This issue has been patched in version 1.15.2.

Affected: Ubuntu:Pro:20.04:LTS: node-axios, Ubuntu:Pro:22.04:LTS: node-axios, Ubuntu:Pro:24.04:LTS: node-axios, Ubuntu:Pro:26.04:LTS: node-axios

Ameer Assadi discovered that Axios did not properly handle certain hostnames when applying NO_PROXY rules. An attacker could possibly use this issue to bypass proxy restrictions and access internal services, resulting in server-side request forgery. (CVE-2025-62718)

It was discovered that Axios did not properly protect certain HTTP header values from prototype pollution. An attacker could possibly use this issue to inject malicious values into outbound requests, resulting in HTTP header injection. (CVE-2026-40175)

Sachin Patil and Amol Patil discovered that Axios did not properly apply NO_PROXY rules to certain loopback addresses. An attacker could possibly use this issue to bypass proxy restrictions and access internal services, resulting in server-side request forgery. (CVE-2026-42043)

Yu Bao discovered that Axios did not properly protect JSON response processing from prototype pollution. An attacker could possibly use this issue to modify values in application responses, resulting in authorization bypass or privilege escalation. This issue only affected Ubuntu 26.04 LTS. (CVE-2026-42044)

It was discovered that Axios did not properly protect certain request configuration options from prototype pollution. An attacker could possibly use this issue to modify outbound HTTP requests, resulting in security restrictions being bypassed. This issue only affected Ubuntu 24.04 LTS and Ubuntu 26.04 LTS.
