FKIE_CVE-2026-105691

Vulnerability from fkie_nvd - Published: 2026-10-05 20:17 - Updated: 2026-10-05 20:17
Severity
9.9 (Critical) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H
Summary
Penpot is an open-source design and prototyping platform. Prior to 2.18.0, the SVG exporter places an attacker-controlled text object's fill-color value into a ppmcolormask command string and executes that string through child_process.exec. A user who can edit a file can store shell metacharacters in the fill color and trigger SVG export, causing commands to execute with the exporter service's privileges. The same export can be triggered through a valid public share link to a malicious file. This vulnerability is fixed in 2.18.0.
