ACF 6.2.5 Security Release: Safeguarding Your WordPress Content

In the ever-evolving landscape of WordPress, security is paramount. Enter ACF 6.2.5, a security release that not only patches vulnerabilities but also brings forth crucial changes to ensure the safety of your site’s content. Let’s delve into the key points that make this update noteworthy.

Important Security Fix:

ACF 6.2.5 addresses a vulnerability where users with the role of contributor or higher, lacking the unfiltered_html permission, could manipulate the value of a custom meta item to inject malicious HTML. This security patch is a crucial shield against potential threats to your WordPress site.

ACF Shortcode Escaping:

Starting from this release, the use of the ACF Shortcode will now be escaped by the WordPress HTML escaping function wp_kses. This change is designed to prevent the output of potentially unsafe HTML, such as scripts or iframes, especially for textarea or WYSIWYG fields.

Upcoming Changes to the_field():

In the imminent ACF 6.2.7 release (expected in late February 2024), the security measures will extend to the functions the_field() and the_sub_field(). While these functions have been reliable for rendering HTML, the upcoming update ensures that they default to outputting safe HTML only. This is a proactive step towards fortifying your site against potential security risks.

Field Type Changes and Customization:

To accommodate diverse use cases, ACF introduces a way for field types to indicate whether they can handle HTML escaping. Developers can use the new parameter $escape_html in get_field() and get_field_object(). This allows customization for specific field types that may require handling HTML escaping themselves.

How to Use ACF Securely:

While ACF strives to enhance security, developers can still output unsafe HTML if needed. For specific scenarios, using echo get_field() and applying the right escaping function is recommended.

echo wp_kses_post( get_field(‘your_field’) );  // Securely outputting the field value

Debugging and Additional Options:

ACF provides actions and filters for debugging instances where unsafe HTML is being removed. Developers can utilize acf/removed_unsafe_html and acf/will_remove_unsafe_html actions for detailed debugging.
