At a glance
CVE-2024-13725 is a critical-severity Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the Keap Official Opt-in Forms WordPress plugin, affecting versions <= 2.0.1. It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 2.0.2; sites on affected versions should update now. Disclosed February 2025, reported by Hiroho Shimada.
Vulnerability Overview
The Keap Official Opt-in Forms plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 2.0.1 via the service parameter. This makes it possible for unauthenticated attackers to include 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. If register_argc_argv is enabled on the server and pearcmd.php is installed, this issue might 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 privileges on the target site, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.
CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Reaching this weakness in Keap Official Opt-in Forms <= 2.0.1 takes no account at all. Path traversal happens when user-controlled text is used to build a filesystem path without being constrained to an intended directory, so sequences like ../ walk the resolved path somewhere else.
Depending on the operation, it means reading files outside the intended folder — wp-config.php being the usual target — or writing to and deleting paths the web server can touch. For Keap Official Opt-in Forms the fix is 2.0.2: builds <= 2.0.1 are affected, anything from 2.0.2 onward is not.
Remediation
Update to version 2.0.2, or a newer patched version
How does WordSec protect against this?
Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Keap Official Opt-in Forms 2.0.2 closes this, and updating the plugin is the step that ends it.
