Penpot 是一款开源的设计与原型设计平台。在 2.18.0 版本之前，get-comment-threads、get-comment-thread 和 get-comments 等 RPC 命令虽然使用了 check-comment-permissions! 进行权限校验，但未正确应用共享链接中的页面范围限制。因此，拥有页面级共享链接的攻击者可以获取同一文件中其他页面的评论线程及完整评论内容，包括评论者的姓名、电子邮件地址、头像和页面标识符。此外，泄露的页面标识符还可结合受影响的页面读取功能，访问未共享的设计内

Vulnerability Title
Penpot: Share-link page-scope escape — comment RPCs leak comment content, author identity, and all page-ids for pages outside the share scope
Source: CVE Program / CVE List V5
Vulnerability Description
Penpot is an open-source design and prototyping platform. Prior to 2.18.0, the get-comment-threads, get-comment-thread, and get-comments RPC commands use check-comment-permissions! but do not apply the share link's pages restriction. A holder of a page-scoped share link can retrieve comment threads and full comment bodies from other pages in the same file, including commenter names, email addresses, photos, and page identifiers. The disclosed page identifiers can also be used with affected page-reading functionality to access unshared design content. This issue is fixed in version 2.18.0.
