At a glance

CVE-2025-12733 is a high-severity Improper Control of Generation of Code ('Code Injection') vulnerability in the WP All Import WordPress plugin, affecting versions <= 3.9.6. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account at Administrator level or above. The issue is fixed in version 4.0.0; sites on affected versions should update now. Disclosed November 2025, reported by tmrswrr.

Vulnerability Overview

The Import any XML, CSV or Excel File to WordPress (WP All Import) plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 3.9.6. This is due to the use of eval() on unsanitized user-supplied input in the pmxi_if function within helpers/functions.php. This makes it possible for authenticated attackers, with import capabilities (typically administrators), to inject and execute arbitrary PHP code on the server via crafted import templates. This can lead to remote code execution.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-94: Improper Control of Generation of Code ('Code Injection')

WP All Import <= 3.9.6 carries this weakness at eval(), and reaching it takes an account at Administrator level or above. Code injection means input from a request reaches a language construct that evaluates code, so the attacker's text is executed rather than treated as data.

The injected code runs with the web server's privileges, giving the attacker the same access to the database and filesystem as WordPress itself. For WP All Import the fix is 4.0.0: builds <= 3.9.6 are affected, anything from 4.0.0 onward is not.

Remediation

Update to version 4.0.0, or a newer patched version

How does WordSec protect against this?

An attacker needs Administrator access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. Classes like this one can leave something behind, so the staged malware scanner is the second half: it looks for dropped files and modified code rather than for the request that created them. None of that substitutes for the fix: WP All Import 4.0.0 closes this, and updating the plugin is the step that ends it.
