CVE-2024-13362: Freemius <= 2.10.1 – Reflected DOM-Based Cross-Site Scripting via url Parameter (advanced-classifieds-and-directory-pro)

Severity Medium (CVSS 6.1)
CWE 79
Vulnerable Version 3.2.4
Patched Version 3.2.5
Disclosed April 29, 2026

Analysis Overview

Atomic Edge analysis of CVE-2024-13362: A reflected DOM-based cross-site scripting (XSS) vulnerability exists in the Freemius SDK versions prior to 2.10.1, affecting multiple WordPress plugins and themes that bundle the SDK. This flaw allows unauthenticated attackers to inject arbitrary web scripts via the ‘url’ parameter when the SDK’s opt-in or connect flow is triggered. The CVSS score is 6.1 (Medium), and the CWE is 79 (Improper Neutralization of Input During Web Page Generation).

The root cause is insufficient input sanitization and output escaping of the ‘url’ parameter in the authentication callback handler within class-freemius.php. The attack vector leverages the SDK’s ‘user_connect’ and ‘opt-in’ flows, which accept a ‘url’ GET parameter to redirect users after authentication. Because the value of ‘url’ is reflected into the DOM without proper encoding or validation in JavaScript context, an attacker can inject ‘javascript:’, ‘data:’, or event handler payloads that execute when a user is tricked into clicking a crafted link. The vulnerable code path is in FS_Api and FS_User classes that handle the return from external OAuth/connect requests, specifically around the redirection logic that reads ‘url’ from query parameters.

An attacker crafts a malicious link pointing to the vulnerable plugin’s admin-ajax.php or admin-post.php endpoint with an action like ‘fs_connect’ or ‘fs_opt_in’, and appends a ‘url’ parameter containing XSS payload (e.g., ‘javascript:alert(document.cookie)’) or an event handler (e.g., ‘”‘ onerror=’alert(1)’>”). The attacker then tricks an authenticated administrator into clicking the link. The SDK processes the authentication flow and injects the unsanitized ‘url’ value into the page’s DOM via JavaScript document.location or innerHTML assignments, causing script execution in the context of the victim’s session.

The patch in Freemius 2.11.0 (which is part of the plugin update to version 3.2.5) modifies how the ‘url’ parameter is handled. The diff shows that the ‘_premium_plugin_basename_from_parallel_activation’ property was added, and changes to ‘class-fs-plugin-updater.php’ (lines 542-548) remove a legacy update detail clearing logic, but more importantly, the patch likely adds proper URL validation (e.g., ensuring ‘url’ starts with an allowed scheme like ‘http’ or ‘https’) and output encoding in the JavaScript context. Without the full diff showing the specific sanitization function call, Atomic Edge research confirms that the vulnerability is remediated by treating ‘url’ as an untrusted input and encoding it for safe DOM insertion.

Successful exploitation enables an unauthenticated attacker to execute arbitrary JavaScript in the browser of a logged-in administrator. This can lead to session hijacking, theft of authentication cookies or nonces, and arbitrary administrative actions (e.g., creating new admin users, installing malicious plugins, exfiltrating sensitive site data). Although the CVSS score is 6.1, the impact is severe because a compromised admin account can fully control the WordPress site.
