CVE-2025-9163Network attack vector

Unauthenticated stored XSS via unsanitized SVG uploads

Published Nov 26, 2025 · Updated Apr 8, 2026

Stored XSS in Favethemes Houzez 4.1.6 and earlier allows remote attackers to inject scripts through uploaded SVG files. The houzez_property_img_upload() and houzez_property_attachment_upload() functions accept SVG content without sufficient sanitization and expose it without adequate output escaping. No authentication is required to store a payload, but script execution requires a user to open the uploaded SVG file in a browser.
