Axios is a promise based HTTP client for the browser and Node.js. From 1.0.0 to before 1.16.0, the Axios library is vulnerable to a Prototype Pollution "Gadget" attack that allows any Object.prototype pollution in the application's dependency tree to be escalated into a full Man-in-the-Middle (MITM) attack — intercepting, reading, and modifying all HTTP traffic including authentication credentials. The HTTP adapter at lib/adapters/http.js:670 reads config.proxy via standard property access, which traverses the prototype chain. Because proxy is not present in Axios defaults, the merged config object has no own proxy property, making it trivially injectable via prototype pollution. Once injected, setProxy() routes all HTTP requests through the attacker's proxy server. This vulnerability is fixed in 1.16.0.

The remote Redhat Enterprise Linux 8 / 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:42078 advisory.

    Red Hat Ansible Automation Platform provides an enterprise framework for building, deploying and managing     IT automation at scale. IT Managers can provide top-down guidelines on how automation is applied to     individual teams, while automation developers retain the freedom to write tasks that leverage existing     knowledge without the overhead. Ansible Automation Platform makes it possible for users across an     organization to share, vet, and manage automation content by means of a simple, powerful, and agentless     language.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux 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 Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2026:0525 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2026-44494:
    Axios is a promise based HTTP client for the browser and Node.js. From 1.0.0 to before 1.16.0, the Axios     library is vulnerable to a Prototype Pollution Gadget attack that allows any Object.prototype pollution     in the application's dependency tree to be escalated into a full Man-in-the-Middle (MITM) attack     intercepting, reading, and modifying all HTTP traffic including authentication credentials.

Because proxy is not present in Axios defaults, the merged config object has no own proxy     property, making it trivially injectable via prototype pollution. Once injected, setProxy() routes all     HTTP requests through the attacker's proxy server. This vulnerability is fixed in 1.16.0.

    CVE-2026-44486:
    Axios is a promise based HTTP client for the browser and Node.js. Prior to 0.32.0 and 1.16.0, Axios'     Node.js HTTP adapter can leak proxy credentials to a redirect target in affected versions. When a request     is sent through an authenticated proxy, Axios may add a Proxy-Authorization header. If Axios then follows     a redirect and the redirected request is no longer sent through that proxy, the stale Proxy-Authorization     header can remain on the redirected request and be sent to the redirect target. This affects Node.js's use     of Axios with automatic redirects enabled and an authenticated proxy configuration. Browser adapters are     not affected. This vulnerability is fixed in 0.32.0 and 1.16.0.

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. From 1.0.0 to before 1.16.0, the Axios     library is vulnerable to a Prototype Pollution Gadget attack that allows any Object.prototype pollution     in the application's dependency tree to be escalated into a full Man-in-the-Middle (MITM) attack     intercepting, reading, and modifying all HTTP traffic including authentication credentials. The HTTP     adapter at lib/adapters/http.js:670 reads config.proxy via standard property access, which traverses the     prototype chain. Because proxy is not present in Axios defaults, the merged config object has no own proxy     property, making it trivially injectable via prototype pollution. Once injected, setProxy() routes all     HTTP requests through the attacker's proxy server. This vulnerability is fixed in 1.16.0. (CVE-2026-44494)

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

The version of the axios Node.js module installed on the remote host is 1.x prior to 1.16.0. It is, therefore, affected by the following vulnerability:

  - A prototype pollution gadget in config.proxy allows any Object.prototype pollution in the application's     dependency tree to be escalated into a full man-in-the-middle attack. The HTTP adapter reads config.proxy     via standard property access which traverses the prototype chain. Because proxy is not present in Axios     defaults, the merged config object has no own proxy property, making it injectable via prototype     pollution. Once injected, setProxy() routes all HTTP requests through the attacker's proxy server,     enabling interception of credentials and response tampering. (CVE-2026-44494)

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