CVE-2026-105694: XSS (CVSS 5.4)

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.
