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 no_proxy hostname normalization bypass is incomplete. When no_proxy=localhost is set, requests to 127.0.0.1 and [::1] still route through the proxy instead of bypassing it. The shouldBypassProxy() function does pure string matching — it does not resolve IP aliases or loopback equivalents. This vulnerability is fixed in 1.15.1 and 0.31.1.

The version of the axios Node.js module installed on the remote host is prior to 1.15.1. It is, therefore, affected by multiple vulnerabilities:

  - Prototype pollution gadgets in axios allow response tampering, data exfiltration, and request hijacking.
    (CVE-2026-42033)

  - Axios' HTTP adapter-streamed uploads bypass maxBodyLength when maxRedirects is set to 0. (CVE-2026-42034)

  - Header injection via prototype pollution in axios. (CVE-2026-42035)

  - Axios HTTP adapter streamed responses bypass maxContentLength. (CVE-2026-42036)

  - Axios no_proxy bypass via IP alias allows SSRF. (CVE-2026-42038)

  - Unbounded recursion in toFormData causes denial of service via deeply nested request data. (CVE-2026-42039)

  - Incomplete fix for CVE-2025-62718 - NO_PROXY protection bypassed via RFC 1122 loopback subnet (127.0.0.0/8)     in axios 1.15.0. (CVE-2026-42043)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - 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
    no_proxy hostname normalization bypass is incomplete. When no_proxy=localhost is set, requests to
    127.0.0.1 and [::1] still route through the proxy instead of bypassing it. The shouldBypassProxy()
    function does pure string matching — it does not resolve IP aliases or loopback equivalents. This
    vulnerability is fixed in 1.15.1 and 0.31.1. (CVE-2026-42038)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.
