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 NO_PROXY protection. This vulnerability is due to an incomplete for CVE-2025-62718, 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.
