CVE-2026-63669: CWE-639: Authorization Bypass Through User-Controlled Key in apostrophecms apostrophe
ApostropheCMS versions prior to 4.32.0 contain an authorization bypass vulnerability in the page module's move() operation. This flaw allows authenticated editors or contributors to move pages into restricted subtrees without proper permission checks, potentially affecting the integrity of protected sibling pages. The issue is fixed in version 4.32.0.
AI Analysis
Technical Summary
The vulnerability in ApostropheCMS (CVE-2026-63669) arises because the move() operation in the page module does not enforce the destination parent's _create permission due to an oldParent archive condition that disables this check for ordinary moves. Authenticated users with editor or contributor roles can exploit this by manipulating the _targetId and _position parameters via the page REST update endpoint to move a controlled page into a restricted subtree. This causes the nudgeNewPeers() function to updateMany, re-ranking protected sibling pages improperly. The vulnerability is resolved in ApostropheCMS version 4.32.0.
Potential Impact
An authenticated editor or contributor can bypass authorization controls to move pages into restricted areas of the content tree, potentially disrupting the intended page hierarchy and affecting the ranking of protected sibling pages. This could lead to unauthorized content manipulation within the CMS.
Mitigation Recommendations
Upgrade ApostropheCMS to version 4.32.0 or later, where this vulnerability has been fixed. No other official remediation or temporary fixes are documented. Patch status is confirmed by the vendor advisory indicating the fix in 4.32.0.
