What is CVE-2026-110813?

The Advanced Custom Fields (ACF) WordPress plugin prior to version 6.8.11 is susceptible to a cross-site scripting (XSS) vulnerability. This occurs due to inadequate sanitization of stored field definitions that can be manipulated via comment handling. Consequently, unauthenticated users are capable of injecting malicious payloads which are subsequently executed as JavaScript in the browsers of visitors and administrators viewing the affected content. This vulnerability poses a significant risk, allowing for potential exploitation and manipulation of the user experience.

Affected Version(s)

Advanced Custom Fields (ACF®) 0 < 6.8.11

Exploit Proof of Concept (PoC)
