Drupal patches critical Field UI RCE via contributed-module paths

Why it matters for readers: This shows how a core admin page bug can become dangerous when combined with third-party modules, so updates matter.

The vulnerability is in Drupal core's Field UI module and can allow remote code execution when reached through contributed modules or custom code.1
Drupal shipped fixes on October 14, 2026 for 11.4.10, 11.3.19 and 10.6.19, and a beta update for Drupal 12.0.0-beta2.1
The advisory says at least one exploit path requires no login and the project rates the issue critical (19/25 on its risk scale).1
The advisory does not name the contributed modules that open exploit paths, and custom code may also expose sites.1
On sites reporting their core version, about 28.5% were on affected branches that received no fix as of the first week of October 2026.1
