Overview

This vulnerability has a CVSS 3.1 base score of 8.7, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

Penpot is an open-source design and prototyping platform. In versions up to and including 2.14.3, Penpot is vulnerable to stored cross-site scripting through file comments, whose content is stored as raw text and rendered into the page with innerHTML without any sanitization. Because the backend applies only a length check and the frontend writes comment content directly through innerHTML, any team member who can comment on a shared file can embed HTML such as an image error handler or script that executes in the browser of every other collaborator. The attack is passive: any user who opens the comments panel on the affected file triggers script execution on the Penpot origin, allowing theft of session cookies, actions performed as the victim, and access to their files and projects. This issue is fixed in version 2.15.3.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
