"The version of jsoup installed on the remote host is prior to 1.6.1-10. It is, therefore, affected by a vulnerability as
referenced in the ALAS2-2024-2466 advisory.

  - jsoup is a Java HTML parser, built for HTML editing, cleaning, scraping, and cross-site scripting (XSS)
    safety. jsoup may incorrectly sanitize HTML including `javascript:` URL expressions, which could allow XSS
    attacks when a reader subsequently clicks that link. If the non-default `SafeList.preserveRelativeLinks`
    option is enabled, HTML including `javascript:` URLs that have been crafted with control characters will
    not be sanitized. If the site that this HTML is published on does not set a Content Security Policy, an
    XSS attack is then possible. This issue is patched in jsoup 1.15.3. Users should upgrade to this version.
    Additionally, as the unsanitized input may have been persisted, old content should be cleaned again using
    the updated version. To remediate this issue without immediately upgrading: - disable
    `SafeList.preserveRelativeLinks`, which will rewrite input URLs as absolute URLs - ensure an appropriate
    [Content Security Policy](https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP) is defined. (This should
    be used regardless of upgrading, as a defence-in-depth best practice.) (CVE-2022-36033)

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