Executive Summary

CVE-2025-12518 is a Stored Cross-site Scripting (XSS) vulnerability in the beefree.io SDK, specifically in the email builder functionality. The issue lies in the Social Media icon URL parameter, where an attacker can inject arbitrary HTML and JavaScript code into the email template.

When a user visits the preview page of the email template, the injected malicious code is rendered and executed. Although beefree.io implements a Content Security Policy (CSP) that limits some payloads from executing, the vulnerability still allows some malicious scripts to run.

This vulnerability affects all versions of the beefree SDK prior to version 3.47.0, where it has been fixed.

Impact Analysis

This vulnerability can impact you by allowing an attacker to inject and execute malicious scripts within the email templates you build using the beefree.io SDK.

Such malicious scripts can lead to unauthorized actions such as stealing user data, session hijacking, or delivering malware when users preview the affected email templates.

Even though the Content Security Policy reduces the risk by blocking some payloads, the vulnerability still poses a significant security risk until the SDK is updated to version 3.47.0 or later.
