Received Received - Intake
Arbitrary File Deletion in Advanced Members for ACF Plugin

Publication date: 2026-04-08

Last updated on: 2026-04-08

Assigner: Wordfence

Description
The Advanced Members for ACF plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the create_crop function in all versions up to, and including, 1.2.5. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). The vulnerability was partially patched in version 1.2.5.

Mitigation Strategies

To mitigate this vulnerability, you should update the Advanced Members for ACF plugin to a version later than 1.2.5, as the vulnerability was partially patched in version 1.2.5.

Additionally, restrict Subscriber-level users from accessing or executing functions that could lead to arbitrary file deletion until the update is applied.

Executive Summary

The Advanced Members for ACF plugin for WordPress has a vulnerability in its create_crop function due to insufficient validation of file paths. This flaw allows authenticated users with Subscriber-level access or higher to delete arbitrary files on the server.

Because the plugin does not properly check the file paths, attackers can specify files to delete beyond what should be allowed, potentially removing critical files such as wp-config.php.

This vulnerability was partially fixed in version 1.2.5, but all versions up to and including 1.2.5 remain affected.

Impact Analysis

This vulnerability can have severe impacts because it allows attackers to delete arbitrary files on the server.

Deleting critical files like wp-config.php can lead to remote code execution, which means attackers could gain full control over the affected WordPress site.

Such control can result in data breaches, site defacement, loss of service, or further exploitation of the server.
