CVE-2025-9163: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in favethemes Houzez
The Houzez theme for WordPress is vulnerable to Stored Cross-Site Scripting via SVG File uploads in all versions up to, and including, 4.1.6 due to insufficient input sanitization and output escaping in the houzez_property_img_upload() and houzez_property_attachment_upload() functions. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses the SVG file.
AI Analysis
Technical Summary
CVE-2025-9163 is a stored cross-site scripting vulnerability in the Houzez WordPress theme (versions up to 4.1.6). The issue is due to improper neutralization of input during web page generation, specifically in the houzez_property_img_upload() and houzez_property_attachment_upload() functions. Attackers can upload crafted SVG files containing malicious scripts, which are then executed in the context of users viewing those files. This vulnerability requires no privileges and has a low attack complexity, but user interaction is needed to trigger the script execution.
Potential Impact
Successful exploitation allows an unauthenticated attacker to execute arbitrary scripts in the browsers of users who access the malicious SVG files. This can lead to information disclosure and integrity impacts within the affected web application context. Availability is not affected. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, it is recommended to restrict or disable SVG file uploads if possible and implement additional input validation and output escaping controls at the application or web server level to mitigate the risk.
