CVE-2025-2505
At a glance
CVE-2025-2505 is a critical-severity Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the Age Gate WordPress plugin, affecting versions <= 3.5.3. 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 3.5.4; sites on affected versions should update now. Disclosed March 2025, reported by mikemyers.
Vulnerability Overview
The Age Gate plugin for WordPress is vulnerable to Local PHP File Inclusion in all versions up to, and including, 3.5.3 via the 'lang' parameter. This makes it possible for unauthenticated attackers to include and execute arbitrary PHP files on the server, allowing the execution of code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where images and other “safe” file types 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 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')
Age Gate <= 3.5.3 carries this weakness at lang, and reaching it 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 Age Gate the fix is 3.5.4: builds <= 3.5.3 are affected, anything from 3.5.4 onward is not.
Remediation
Update to version 3.5.4, 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: Age Gate 3.5.4 closes this, and updating the plugin is the step that ends it.
