axios before 0.33.0 (and 1.x before 1.18.0) can consume inherited properties from nested request option objects when the JavaScript process's Object.prototype has already been polluted by another component. While the top-level merged config uses a null prototype, nested plain objects such as auth and paramsSerializer are cloned into ordinary objects and read without own-property checks. When an application passes placeholder nested objects such as auth: {} or paramsSerializer: {}, inherited username/password values can cause silent injection of an Authorization: Basic header, and inherited encode/serialize values can alter query-string serialization (full serializer replacement requires a function-valued pollution primitive). This is exploitable only in the presence of pre-existing prototype pollution.

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

  - axios before 0.33.0 (and 1.x before 1.18.0) can consume inherited properties from nested request option
    objects when the JavaScript process's Object.prototype has already been polluted by another component.
    While the top-level merged config uses a null prototype, nested plain objects such as auth and
    paramsSerializer are cloned into ordinary objects and read without own-property checks. When an
    application passes placeholder nested objects such as auth: {} or paramsSerializer: {}, inherited
    username/password values can cause silent injection of an Authorization: Basic header, and inherited
    encode/serialize values can alter query-string serialization (full serializer replacement requires a
    function-valued pollution primitive). This is exploitable only in the presence of pre-existing prototype
    pollution. (CVE-2026-67319)

The version of the axios Node.js module installed on the remote host is prior to 0.33.0 or 1.x prior to 1.18.0. It is, therefore, affected by multiple vulnerabilities:

  - axios is vulnerable to read-side prototype-pollution gadgets that can alter request construction when     Object.prototype has already been polluted by a separate vulnerability or dependency. In the bodyless method     aliases, inherited data is read via (config || {}).data before config normalization, causing an     attacker-controlled body to be sent on requests that did not set one. (CVE-2026-67316)

  - axios can consume inherited properties from nested request option objects when the JavaScript process's     Object.prototype has already been polluted by another component. Nested plain objects such as auth and     paramsSerializer are cloned into ordinary objects and read without own-property checks. (CVE-2026-67319)

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

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

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