CVE-2022-43717Network attack vector

Dashboard XSS via incomplete Markdown sanitization

Published Jan 16, 2023 · Updated Apr 4, 2025

Cross-site scripting in Apache Superset 1.5.2 and earlier and 2.0.0 allows remote authenticated users to run script via dashboards. The SafeMarkdown component rendered raw HTML after rejecting only quoted href or src values using javascript, vbscript, or file schemes. Dashboard-creation permission is required, and another user must render the crafted Markdown for script execution in that user's browser context.
