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， RPC 接口允许使用带有广泛读取权限的分享链接访问对象，但未验证调用者指定的页面 ID 是否属于该链接所授权的页面集合。因此，如果攻击者同时拥有一个有效的分享链接和自己的已认证 Penpot 会话，并且知道目标页面的标识符，即可通过需认证的 接口获取同一文件中其他页面的完整形状和设计数据。此外，相关的 RPC 接口也允许通过分享链接访问文件片段，但未将片段映射到受授权的页面。该问题已在版本 2.18.0 中得到修复。

Vulnerability Title
Penpot: Share-link page-scope escalation: a share-link holder reads pages outside the link's authorized scope via the get-page RPC command
Source: CVE Program / CVE List V5
Vulnerability Description
Penpot is an open-source design and prototyping platform. Prior to 2.18.0, the get-page RPC accepts a share-link permission object with blanket read access but does not verify that the caller-selected page-id belongs to the link's authorized pages set. An attacker with both a valid share link and the attacker's own authenticated Penpot session can retrieve the complete shape and design data of another page in the same file when its identifier is known, because get-page requires authentication. The related get-file-fragment RPC also permits share-link access without mapping fragments to authorized pages. This issue is fixed in version 2.18.0.
