  • Published2026-11-06
  • WeaknessCWE-79

Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

Description

The Advanced Custom Fields (ACF®) WordPress plugin before 6.8.11 does not properly sanitize a stored field definition that can be modified through its comment handling, allowing unauthenticated users to inject a payload that is emitted as an HTML attribute name and executed as JavaScript in the browser of any visitor or administrator who views a page rendering the affected field.
