CVE-2024-13362: Freemius <= 2.10.1 – Reflected DOM-Based Cross-Site Scripting via url Parameter (bp-better-messages)

Severity Medium (CVSS 6.1)
CWE 79
Vulnerable Version 2.6.7
Patched Version 2.7.0
Disclosed April 29, 2026

Analysis Overview

Atomic Edge analysis of CVE-2024-13362: The Freemius SDK bundled in WordPress plugins and themes is vulnerable to Reflected DOM-Based Cross-Site Scripting via the `url` parameter. The vulnerability stems from insufficient input sanitization and output escaping in the `wp_freemius.php` file, version 2.10.1 and earlier. This allows unauthenticated attackers to inject arbitrary web scripts.

Root Cause: The vulnerability exists in the Freemius SDK, specifically in the `wp_freemius.php` file. The SDK processes a `url` parameter from the request without proper sanitization or escaping before inserting it into the DOM. The affected code path in the diff is primarily in `bp-better-messages/bp-better-messages.php` and its addons, where version updates and settings changes are made, but the core issue is in the Freemius SDK’s handling of the `url` parameter for redirect or modal operations. The SDK’s `addons/onesignal.php` and `addons/files.php` also reflect similar insufficient input handling.

Exploitation: An attacker crafts a malicious link containing a `url` parameter with a JavaScript payload, such as `javascript:alert(document.cookie)` or a data URIs scheme. When a victim clicks the link, the vulnerable plugin processes the `url` parameter without escaping, causing the script to execute in the victim’s browser. The attack vector is reflected XSS, requiring user interaction (clicking a crafted link). The payload is injected via the `url` parameter in a GET request to a page that includes the Freemius SDK’s output.

Patch Analysis: The patch in the diff addresses multiple components but the XSS fix specifically involves adding output escaping or removing unsafe echo statements. For example, in `bp-better-messages/bp-better-messages.php`, the version string is now properly handled, and in `addons/onesignal.php`, the script URL is now more strictly validated. However, the primary fix for the Freemius SDK itself would involve sanitizing the `url` parameter with `esc_url()` or `wp_kses()` before output. The diff also shows changes to plugin version and settings defaults, which are not the XSS fix but part of a larger update.

Impact: Successful exploitation allows an attacker to execute arbitrary JavaScript in the context of a victim’s WordPress admin or frontend session. This can lead to session hijacking, defacement, theft of sensitive information (e.g., cookies, nonces), or further privilege escalation by tricking an admin into performing actions. The CVSS score of 6.1 reflects medium severity due to the requirement for user interaction.
