## What is CVE-2026-3243?

CVE-2026-3243 is a high-severity path traversal vulnerability in danbilabs Advanced Members for ACF, published on 8 Apr 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official 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.

Weakness: CWE-22 (Improper Limitation of a Pathname to a Restricted Directory)
