What is CVE-2026-97191?

The Advanced Custom Fields (ACF) plugin for WordPress prior to version 6.8.11 presents an access control vulnerability that enables users with contributor-level access and higher to manipulate custom fields typically reserved for administrators. This is achieved by bypassing the expected location rules during the saving process through the post editor, thereby allowing unauthorized modifications to be written to their own posts.

Affected Version(s)

Advanced Custom Fields (ACF®) 0 < 6.8.11

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
