Recommendation: Monitor — no exploitation signal at the moment.
A flaw was found in Quay. The filedrop endpoint accepts any mime type without validation, allowing an authenticated user with repository write access to upload a malicious SVG file containing JavaScript. The file is stored and served inline through the CDN, enabling stored cross-site scripting when a victim visits the archive URL.
