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

  - 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)

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.

    It was discovered that url-parse incorrectly handled certain inputs. If a user or an automated system were     tricked into opening a specially crafted input file, a remote attacker could possibly use this issue to     cause a denial of service, or to perform a server-side request forgery attack or open redirect attack.
    (CVE-2018-3774)

    It was discovered that url-parse incorrectly handled certain inputs. If a user or an automated system were     tricked into opening a specially crafted input file, a remote attacker could possibly use this issue to     bypass input validation. This issue was only fixed in Ubuntu 18.04 LTS and Ubuntu 20.04 LTS.

    Package        : node-url-parse     Version        : 1.2.0-2+deb10u2     CVE ID         : CVE-2021-3664 CVE-2021-27515 CVE-2022-0512 CVE-2022-0639                      CVE-2022-0686 CVE-2022-0691     Debian Bug     : 985110 991577

    Multiple vulnerabilities were found in node-types-url-parse, a Node.js     module used to parse URLs, which may result in authorization bypass or     redirection to untrusted sites.

    CVE-2021-3664

        url-parse mishandles certain uses of a single (back)slash such as         https:\ & https:/ and interprets the URI as a relative path.
        Browsers accept a single backslash after the protocol, and treat it         as a normal slash, while url-parse sees it as a relative path.
        Depending on library usage, this may result in allow/block list         bypasses, SSRF attacks, open redirects, or other undesired behavior.

    CVE-2021-27515

        Using backslash in the protocol is valid in the browser, while         url-parse thinks it's a relative path.  An application that         validates a URL using url-parse might pass a malicious link.

    CVE-2022-0512

        Incorrect handling of username and password can lead to failure to         properly identify the hostname, which in turn could result in         authorization bypass.

    CVE-2022-0639

        Incorrect conversion of `@` characters in protocol in the `href`         field can lead to lead to failure to properly identify the hostname,         which in turn could result in authorization bypass.

    CVE-2022-0686

        Rohan Sharma reported that url-parse is unable to find the correct         hostname when no port number is provided in the URL, such as in         `http://example.com:`.  This could in turn result in SSRF attacks,         open redirects or any other vulnerability which depends on the         `hostname` field of parsed URL.

    CVE-2022-0691

        url-parse is unable to find the correct hostname when the URL         contains a backspace `\b` character.  This tricks the parser into         interpreting the URL as a relative path, bypassing all hostname         checks.  It can also lead to false positive in `extractProtocol()`.

    For Debian 10 buster, these problems have been fixed in version     1.2.0-2+deb10u2.

    We recommend that you upgrade your node-url-parse packages.
