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

  - 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 checking of the data     payload, where if Object.prototype is polluted with getHeaders, append, pipe, on, once, and     Symbol.toStringTag, Axios misidentifies any plain object payload as a FormData instance and calls the     attacker-controlled getHeaders() function, merging the returned headers into the outgoing request. The     vulnerable code resides exclusively in lib/adapters/http.js. The prototype pollution source does not need     to originate from Axios itself  any prototype pollution primitive in any dependency in the application's     dependency tree is sufficient to trigger this gadget. This vulnerability is fixed in 1.15.1 and 0.31.1.
    (CVE-2026-42035)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Fedora 44 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-cb5661d883 advisory.

    33.0.3 Release

Tenable has extracted the preceding description block directly from the Fedora security advisory.

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

The remote Fedora 43 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-6599e30e04 advisory.

    33.0.3 Release

Tenable has extracted the preceding description block directly from the Fedora security advisory.

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

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.

The remote Fedora 42 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-2fed8dd674 advisory.

    33.0.3 Release

Tenable has extracted the preceding description block directly from the Fedora security advisory.

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