Description

The ARForms plugin for WordPress is vulnerable to arbitrary file upload in all versions up to, and including, 7.2.4 via its form file-upload handler. The name of the stored file is taken from an attacker-controlled request header and is not adequately restricted to safe file types, and the plugin's file-type and content-safety checks can be evaded, allowing files that contain executable PHP code to be written to a publicly accessible directory. This makes it possible for unauthenticated attackers to upload malicious files to the affected site's server, which may make remote code execution possible. Exploitation requires a published form containing a File field to be publicly accessible on the site.

Detection & mitigation playbook

Vulnerability

  1. Detect

    Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).

  2. Remediation status

    The records we use list no fixed release for CVE-2026-111190. Check the upstream advisory for a patched version, and apply the exposure-reduction steps below in the meantime.

  3. Mitigate without a patch

    Treat uploaded files as untrusted until proven otherwise: validate the actual content type rather than the supplied extension, store uploads outside the web root on a volume mounted without execute permission, and rename them to server-generated identifiers so an attacker cannot choose the path a request will later resolve.
