The remote Debian 10 host has a package installed that is affected by a vulnerability as referenced in the dla-3665 advisory.

  - JSON5 is an extension to the popular JSON file format that aims to be easier to write and maintain by hand     (e.g. for config files). The `parse` method of the JSON5 library before and including versions 1.0.1 and     2.2.1 does not restrict parsing of keys named `__proto__`, allowing specially crafted strings to pollute     the prototype of the resulting object. This vulnerability pollutes the prototype of the object returned by     `JSON5.parse` and not the global Object prototype, which is the commonly understood definition of     Prototype Pollution. However, polluting the prototype of a single object can have significant security     impact for an application if the object is later used in trusted operations. This vulnerability could     allow an attacker to set arbitrary and unexpected keys on the object returned from `JSON5.parse`. The     actual impact will depend on how applications utilize the returned object and how they filter unwanted     keys, but could include denial of service, cross-site scripting, elevation of privilege, and in extreme     cases, remote code execution. `JSON5.parse` should restrict parsing of `__proto__` keys when parsing JSON     strings to objects. As a point of reference, the `JSON.parse` method included in JavaScript ignores     `__proto__` keys. Simply changing `JSON5.parse` to `JSON.parse` in the examples above mitigates this     vulnerability. This vulnerability is patched in json5 versions 1.0.2, 2.2.2, and later. (CVE-2022-46175)

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