Stored XSS via unsanitized SVG product images

Published Aug 10, 2025 · Updated Aug 12, 2025

Stored XSS in oitcode Samarium 0.9.0 through 0.9.6 allows remote attackers to execute JavaScript via a crafted product image. The product-image upload accepts and stores SVG content without validation or sanitization, allowing embedded scripts to run in a browser. Execution requires a user to view the uploaded image and exposes data available to scripts in that user's application origin, including accessible session tokens.
