According to its self-reported version number, the detected Drupal application is affected by multiple vulnerabilities:

- The Image module fails to adequately validate access permissions for image style derivatives when served through non-private file streams, potentially resulting in information disclosure when Drupal is configured to use a contributed non-core file scheme. (CVE-2026-15916)

- The XSS filter in Drupal core fails to sufficiently sanitize certain HTMX attributes, allowing an attacker with the ability to insert HTML to trigger a cross-site scripting (XSS) attack. (CVE-2026-15917)

- The Layout Builder module fails to sufficiently sanitize block labels in certain scenarios where both the attacker and target have access to Layout Builder editing, which can lead to a cross-site scripting (XSS) vulnerability. (CVE-2026-55805)

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

According to its self-reported version, the instance of Drupal running on the remote web server is 10.6.x prior to 10.6.13, 11.3.x prior to 11.3.14, or 11.4.x prior to 11.4.4. It is, therefore, affected by multiple vulnerabilities.

  - Drupal core 11.2 and above integrate the HTMX JavaScript library. Drupal core's XSS filter does not     sufficiently sanitize certain HTMX attributes, which can lead to a cross-site scripting (XSS)     vulnerability. The vulnerability is mitigated by the fact an attacker must be able to insert HTML with     specific attributes. (CVE-2026-15917)

  - The Layout Builder module doesn't sufficiently sanitize block labels in certain scenarios, which can lead     to a cross-site scripting (XSS) vulnerability. This is mitigated by the fact that both the attacker and     the targeted user need to be using the Layout Builder editing interface. (CVE-2026-55805)

  - The Image module allows you to define and configure image fields. The module doesn't sufficiently check     access to image style derivatives when those files are served via a file stream other than private://.
    This vulnerability is mitigated by the fact that Drupal must be configured to use a contributed (non-core)     file scheme to serve private derived images. Information disclosure issues like this one are not generally     given security advisories (as described in PSA-2023-07-12)). This fix is provided as a hardening.
    Contributed modules implementing custom stream wrappers may need to add similar hardenings.

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