# CVE-2026-63669: ApostropheCMS: Missing destination-parent authorization in page \`move()\` allows a low-privileged editor to move and re-rank pages inside a restricted subtree

- Also known as: GHSA-WR5R-WQP2-X4FH
- Severity: CVSS 6.5 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 4.32.0

## Affected

- apostrophecms apostrophe: fixed in 4.32.0
- apostrophe (npm): fixed in 4.32.0

## Description

ApostropheCMS is an open-source Node.js content management system. Prior to 4.32.0, the page module's move() operation fails to enforce the destination parent's _create permission because its oldParent archive condition disables the check for ordinary moves, allowing an authenticated editor or contributor to use _targetId and _position through the page REST update endpoint to move a controlled page into a restricted subtree and make nudgeNewPeers() updateMany re-rank protected sibling pages. This issue is fixed in version 4.32.0.
