CVE-2023-46744
CVSS 3.1 Score 5.4 of 10 (medium)
Details
Summary
CVE-2023-46744 is a stored Cross-Site Scripting (XSS) vulnerability affecting Squidex, an open-source headless CMS and content management hub. Authenticated users with the "assets.create" permission can exploit this weakness by uploading a malicious SVG asset, bypassing Squidex's SVG filtering mechanism. The filtering process checks for malicious HTML tags and attributes, specifically "script" and "on" prefixes. However, adversaries can introduce other HTML elements, such as an <iframe> with a "javascript:" value, to execute arbitrary JavaScript code, leading to privilege escalation and potential targeting of registered users within the Squidex CMS.
