"The remote Ubuntu 16.04 ESM / 18.04 LTS / 20.04 LTS host has a package installed that is affected by multiple
vulnerabilities as referenced in the USN-5973-1 advisory.

  - Incorrect parsing in url-parse <1.4.3 returns wrong hostname which leads to multiple vulnerabilities such
    as SSRF, Open Redirect, Bypass Authentication Protocol. (CVE-2018-3774)

  - Insufficient validation and sanitization of user input exists in url-parse npm package version 1.4.4 and
    earlier may allow attacker to bypass security checks. (CVE-2020-8124)

  - url-parse before 1.5.0 mishandles certain uses of backslash such as http:\/ and interprets the URI as a
    relative path. (CVE-2021-27515)

  - url-parse is vulnerable to URL Redirection to Untrusted Site (CVE-2021-3664)

  - Authorization Bypass Through User-Controlled Key in NPM url-parse prior to 1.5.6. (CVE-2022-0512)

  - Authorization Bypass Through User-Controlled Key in NPM url-parse prior to 1.5.7. (CVE-2022-0639)

  - Authorization Bypass Through User-Controlled Key in NPM url-parse prior to 1.5.8. (CVE-2022-0686)

  - Authorization Bypass Through User-Controlled Key in NPM url-parse prior to 1.5.9. (CVE-2022-0691)

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