Title
Advanced Custom Fields (ACF®) <= 6.8.1 - Unauthenticated Arbitrary Post Modification via Front-End Form '_post_title' and '_post_content' Parameters
Summary
The Advanced Custom Fields (ACF®) plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 6.8.1. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to overwrite the post_title and post_content of any post bound to a publicly accessible acf_form() instance by injecting values into the _post_title and _post_content parameters of a form submission request.

CVE-2026-4812 (GCVE-0-2026-4812)

Vulnerability from nvd – Published: 2026-04-15 01:25 – Updated: 2026-04-15 16:01

Title
Advanced Custom Fields (ACF®) <= 6.7.0 - Unauthenticated Missing Authorization to Arbitrary Post/Page Disclosure via AJAX Field Query Parameters
Summary
The Advanced Custom Fields (ACF) plugin for WordPress is vulnerable to Missing Authorization to Arbitrary Post/Page Disclosure in versions up to and including 6.7.0. This is due to AJAX field query endpoints accepting user-supplied filter parameters that override field-configured restrictions without proper authorization checks. This makes it possible for unauthenticated attackers with access to a frontend ACF form to enumerate and disclose information about draft/private posts, restricted post types, and other data that should be restricted by field configuration.

Title
Advanced Custom Fields <= 6.2.4 - Authenticated (Contributor+) Stored Cross-Site Scripting via Custom Field
Summary
The Advanced Custom Fields (ACF) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via a custom text field in all versions up to, and including, 6.2.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

CVE-2026-8382 (GCVE-0-2026-8382)

Vulnerability from cvelistv5 – Published: 2026-05-31 02:28 – Updated: 2026-06-01 10:33

Title
Advanced Custom Fields (ACF®) <= 6.8.1 - Unauthenticated Arbitrary Post Modification via Front-End Form '_post_title' and '_post_content' Parameters
Summary
The Advanced Custom Fields (ACF®) plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 6.8.1. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to overwrite the post_title and post_content of any post bound to a publicly accessible acf_form() instance by injecting values into the _post_title and _post_content parameters of a form submission request.

Title
Advanced Custom Fields (ACF®) <= 6.7.0 - Unauthenticated Missing Authorization to Arbitrary Post/Page Disclosure via AJAX Field Query Parameters
Summary
The Advanced Custom Fields (ACF) plugin for WordPress is vulnerable to Missing Authorization to Arbitrary Post/Page Disclosure in versions up to and including 6.7.0. This is due to AJAX field query endpoints accepting user-supplied filter parameters that override field-configured restrictions without proper authorization checks. This makes it possible for unauthenticated attackers with access to a frontend ACF form to enumerate and disclose information about draft/private posts, restricted post types, and other data that should be restricted by field configuration.

Title
Advanced Custom Fields <= 6.2.4 - Authenticated (Contributor+) Stored Cross-Site Scripting via Custom Field
Summary
The Advanced Custom Fields (ACF) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via a custom text field in all versions up to, and including, 6.2.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
