CVE-2026-38948 Details
Description
Cross-Site Scripting (XSS) vulnerability exists in FUEL CMS v1.5.2 and before within the asset upload functionality. The application fails to properly sanitize uploaded SVG files, allowing a low-privileged authenticated user to upload a crafted SVG file containing malicious code.
A stored Cross-Site Scripting (XSS) vulnerability has been identified in FUEL CMS versions through 1.5.2, specifically within the asset upload feature. The vulnerability arises because the application does not adequately sanitize uploaded SVG files. This flaw allows low-privileged authenticated users to upload SVG files embedded with malicious JavaScript. Once uploaded, these files are stored without proper cleaning, and the embedded scripts execute when an administrator views or previews the file. This exploitation can lead to unauthorized access to the administrator's account and sensitive data.
