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 是一款开源的设计与原型制作平台。在 2.18.0 版本之前， RPC 接口会接收调用方指定的共享链接 ID，但仅验证调用方是否拥有对该父文件的编辑权限。它并未验证调用方是否是该共享链接的创建者，也未曾检查其是否具备所有者或管理员权限。因此，任何知晓共享链接 UUID 的文件编辑者均可删除由其他用户创建的共享链接，从而撤销外部审阅者的访问权限。该问题已在 2.18.0 版本中修复。

Vulnerability Title
Penpot: IDOR in Share-Link Deletion Allows Any File Editor to Delete Share-Links They Did Not Create
Source: CVE Program / CVE List V5
Vulnerability Description
Penpot is an open-source design and prototyping platform. Prior to 2.18.0, the delete-share-link RPC retrieves a caller-selected share-link ID and verifies only that the caller can edit the parent file. It does not verify that the caller created the share link or has owner or administrator authority, allowing any file editor who knows a share-link UUID to delete links created by other users and revoke external reviewers' access. This issue is fixed in version 2.18.0.
