Summary

Penpot before 2.18.0 stores uploaded SVG media without sanitization, keeping scripts, event-handler attributes and foreignObject elements (CWE-79). An authenticated user with file-edit permission can upload such a file, and when a victim opens its asset URL, the script runs in the Penpot origin with the victim's session authority. The attacker can then make requests and access data as that victim.

Description from the CNA

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.
