CVE-2024-5567: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in MuffinGroup Betheme
The Betheme theme for WordPress is vulnerable to Stored Cross-Site Scripting via SVG File uploads in all versions up to, and including, 27.5.5 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the SVG file.
AI Analysis
Technical Summary
The Betheme WordPress theme suffers from a stored XSS vulnerability due to improper neutralization of input during web page generation (CWE-79). Specifically, SVG file uploads are not properly sanitized or escaped, enabling authenticated users with Contributor or higher privileges to embed arbitrary scripts. These scripts execute in the context of users viewing the SVG, potentially leading to information disclosure or session hijacking. The vulnerability affects all versions up to 27.5.5. No vendor patch or remediation details are available in the provided data.
Potential Impact
An attacker with Contributor-level or higher access can inject malicious JavaScript via SVG file uploads. This script executes whenever a user accesses the SVG, potentially leading to unauthorized actions such as session hijacking or data theft. The impact is limited to confidentiality and integrity, with no direct availability impact reported. The CVSS score of 6.4 reflects a medium severity vulnerability with network attack vector, low attack complexity, and no user interaction required.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict Contributor-level access to trusted users only and consider disabling SVG uploads if possible. Monitor for updates from MuffinGroup regarding patches or official mitigations.
