Penpot: Stored XSS via Unsanitised SVG Uploads

Published Oct 5, 2026 CVSS 3.1 · 5.4 Medium EPSS < 1% KEV · Not listed
Description
Penpot is an open-source design and prototyping platform. Prior to 2.18.0, authenticated users with file-edit permission can upload SVG media whose scripts, event-handler attributes, and foreignObject elements are stored without sanitization and served as image/svg+xml from the Penpot origin. A victim who navigates to the asset URL executes attacker-controlled JavaScript in that origin, allowing requests and data access with the victim's Penpot session authority. This issue is fixed in version 2.18.0.
