At a glance
CVE-2024-10898 is a high-severity Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') vulnerability in the Email Addon for Contact Form 7 WordPress plugin, affecting versions <= 1.9. 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 Contributor level or above. The issue is fixed in version 2.0; sites on affected versions should update now. Disclosed November 2024, reported by Le Ngoc Anh.
Vulnerability Overview
The Contact Form 7 Email Add on plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 1.9 via the cf7_email_add_on_add_admin_template() function. This makes it possible for authenticated attackers, with Contributor-level access and above, to include and execute arbitrary PHP files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where php files can be uploaded and included.
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-98: Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion')
Email Addon for Contact Form 7 <= 1.9 carries this weakness at cf7_email_add_on_add_admin_template(), and reaching it takes an account at Contributor level or above. PHP file inclusion means a path used by include or require is built from request data, so the file that gets executed is under the caller's influence.
Including an attacker-influenced file executes its contents, which is why this class is routinely chained with an upload or log-poisoning step to reach code execution. For Email Addon for Contact Form 7 the fix is 2.0: builds <= 1.9 are affected, anything from 2.0 onward is not.
Remediation
Update to version 2.0, or a newer patched version
How does WordSec protect against this?
An attacker needs Contributor 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: Email Addon for Contact Form 7 2.0 closes this, and updating the plugin is the step that ends it.
