"The remote Debian 10 host has a package installed that is affected by multiple vulnerabilities as referenced in the
dla-3221 advisory.

  - A prototype pollution attack in cached-path-relative versions <=1.0.1 allows an attacker to inject
    properties on Object.prototype which are then inherited by all the JS objects through the prototype chain
    causing a DoS attack. (CVE-2018-16472)

  - The package cached-path-relative before 1.1.0 are vulnerable to Prototype Pollution via the cache variable
    that is set as {} instead of Object.create(null) in the cachedPathRelative function, which allows access
    to the parent prototype properties when the object is used to create the cached relative path. When using
    the origin path as __proto__, the attribute of the object is accessed instead of a path. **Note:** This
    vulnerability derives from an incomplete fix in https://security.snyk.io/vuln/SNYK-JS-
    CACHEDPATHRELATIVE-72573 (CVE-2021-23518)

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