Use of Externally-Controlled Input to Select Classes or Code ('Unsafe Reflection') vulnerability in Drupal Drupal core allows Reflection Injection. This issue affects Drupal core versions: from 8.9.0 to 10.6.19, from 11.0.0 to 11.3.19, from 11.4.0 to 11.4.10, from 12.0.0-alpha1 to 12.0.0-beta2.

Drupal warns of a RCE flaw in the Field UI module in Drupal Core. Multiple exploit paths via contributed modules, with one not requiring auth. Upgrade as soon as possible.

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 3de00266-caf6-11f1-881f-d89ef317b2fc advisory.

    Drupal core reports:

              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.


Tenable has extracted the preceding description block directly from the FreeBSD security advisory.

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

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

 - A vulnerability in the Drupal core Field UI module can lead to remote code execution. While not directly exploitable with core alone, multiple serious exploit paths exist with contributed modules, and at least one known exploit requires no authentication. (CVE-2026-108097)

 - The Drupal core Link module does not sufficiently sanitize certain markup in some circumstances, which can lead to a cross-site scripting (XSS) vulnerability. (CVE-2026-108515)

 - The Drupal core Navigation module does not sufficiently sanitize certain attributes, which can lead to a cross-site scripting (XSS) vulnerability. Exploitation requires a role with specific HTML entry permissions or administrative menu access. (CVE-2026-108514)

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 10.6.19, 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)
