Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Penpot 是一个开源的设计与原型制作平台。在版本 2.18.0 之前，SVG 导出功能会将攻击者可控的文本对象的颜色填充值插入到 ppmcolormask 命令字符串中，并通过 child_process.exec 执行该字符串。能够编辑文件的用户可以在填充颜色中嵌入 Shell 元字符，并触发 SVG 导出，从而以导出服务的权限执行任意命令。此外，通过指向恶意文件的有效公开分享链接，也可触发相同的导出操作。此漏洞已在版本 2.18.0 中得到修复。

Vulnerability Title
Penpot: Authenticated OS Command Injection in Penpot SVG Exporter via Legacy fill-color
Source: CVE Program / CVE List V5
Vulnerability Description
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.
