CVE-2026-113655— ApostropheCMS: Same-parent page reorder in @apostrophecms/page move() re-ranks a restricted parent's children without create authorization

Quick assessment

Affected
apostrophecms apostrophe
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.

ApostropheCMS 是一个开源的基于 Node.js 的内容管理系统。在 4.33.0 版本之前，拥有合法编辑权限的已认证编辑者，若对某个受限制父页面下已存在的普通子页面具有编辑权，即可利用“同父页面移动”操作，在无需对该父页面拥有创建权限的情况下，修改兄弟页面的排序层级。此漏洞利用的前提是：非默认的嵌套结构必须已预先存在；其绕过范围仅限于兄弟页面的排序调整，无法实现任意内容修改、机密信息泄露或创建受限制的嵌套结构。该问题已在 4.33.0 版本中修复。

Vulnerability Title
ApostropheCMS: Same-parent page reorder in @apostrophecms/page move() re-ranks a restricted parent's children without create authorization
Source: CVE Program / CVE List V5
Vulnerability Description
ApostropheCMS is an open-source Node.js content management system. Prior to 4.33.0, an authenticated editor with legitimate edit rights on a pre-existing ordinary page nested under a restricted parent can use the same-parent page move operation to change sibling ranks without create authorization on that parent. The non-default nesting must already exist, and the bypass is limited to sibling ordering rather than arbitrary content modification, confidentiality loss, or creation of the restricted nesting. This issue is fixed in version 4.33.0.
