AI Analysis

Impact

The vulnerability is a Stored Cross‑Site Scripting (XSS) flaw in the Social Media icon URL parameter within the Beefree SDK email builder. A malicious attacker can inject arbitrary HTML and JavaScript into a template, and the injected code is rendered and executed when a preview page is viewed. Although the SDK implements a Content Security Policy that limits execution of certain payloads, some scripts may still run, enabling an attacker to steal session cookies, deface content, or redirect users. The weakness is classified as CWE‑79 and carries a CVSS score of 5.3, indicating moderate severity.

Affected Systems

The affected vendor is Bee Content Design, product Befree SDK. All releases prior to version 3.47.0 are susceptible. The issue was fixed in SDK version 3.47.0, so any deployments using 3.46.x or earlier are impacted.

Risk and Exploitability

With a CVSS score of 5.3 and no EPSS data, the risk is considered moderate. The vulnerability requires access to the template preview functionality, which may be limited to users with appropriate permissions. It is not listed in the CISA Known Exploited Vulnerabilities catalog. Since the flaw allows execution of arbitrary client‑side code, its exploitability is high for users who can view or share preview links, while exploitation in fully isolated environments is lower.
