What to do

Update, patch or deactivate.

Update Advanced Members for ACF to a release after 1.2.5, or disable and remove it until a fixed version is available.

A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.

Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.

Source record

Technical 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.
