Description · from the CVE record

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.
