"According to its self-reported version, the instance of Drupal running on the remote web server is 10.6.x prior to
10.6.19, 11.3.x prior to 11.3.19, or 11.4.x prior to 11.4.10. It is, therefore, affected by multiple vulnerabilities.

  - The Drupal core Link module provides a field type that can be used for internal and external URLs. The
    module does not sufficiently sanitize certain markup in some circumstances, which can lead to cross-site
    scripting (XSS) vulnerabilities. (CVE-2026-108515)

  - The Navigation module doesn't sufficiently sanitize certain attributes, which can lead to a cross-site
    scripting (XSS) vulnerability. This vulnerability is mitigated by the fact that an attacker must have a
    role with permission to enter HTML tags containing specific data attributes, or the administer menu
    permission. (CVE-2026-108514)

  - A remote code execution vulnerability exists within the Field UI module in Drupal core. The vulnerability
    is not directly exploitable with core alone, but multiple serious exploit paths exist with contributed
    modules. At least one known exploit path does not require authentication. Custom code may also expose the
    vulnerable functionality. The vulnerability can be mitigated by uninstalling the core Field UI module
    (field_ui), which will provide protection while sites are updated. Drupal Steward protection: This issue
    is being protected by Drupal Steward. Sites that use Drupal Steward are already protected from some known
    attack vectors, but the protection offered will not cover all possible exploits. Sites should upgrade in
    the near future in case additional attack vectors are discovered. (CVE-2026-108097)

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