CVE-2026-48015Network attack vector

Stored XSS via unsanitized SVG uploads

Published Jul 17, 2026 · Updated Jul 17, 2026

Stored XSS in Shopware before 6.6.10.18 and 6.7.0.0 through 6.7.10.0 allows remote authenticated users to execute JavaScript via SVG uploads. The media upload pipeline classifies whitelisted SVG files as vector graphics but does not strip scripts, event handlers, foreign objects, or external references. Administrator access is required to upload the file; JavaScript runs in the Shopware origin when the SVG is accessed, exposing session-accessible data.
