CVE-2026-50280: CWE-284: Improper Access Control in craftcms cms
Craft CMS is a content management system (CMS). In versions 5.0.0-RC1 and above prior to 5.9.21, the EntriesController::actionMoveToSection() endpoint gates the destination section only by viewEntries:$section->uid rather than requiring saveEntries permission (the source entry is separately checked via Entry::canMove()). As a result, a low-privileged authenticated control-panel user who can move an entry out of its current section can call moveEntryToSection() to rewrite the entry's sectionId and save it into a section where they have read access but no write access. This breaks the section-level authorization model, letting a user with limited permissions inject content into a protected section and interfere with editorial boundaries, approval workflows, and section-specific business logic. This issue has been fixed in version 5.9.21.
AI Analysis
Technical Summary
The vulnerability in Craft CMS arises because the actionMoveToSection() endpoint checks the destination section only by the viewEntries permission rather than the required saveEntries permission. Although the source entry's move permission is verified, the destination section authorization is insufficiently enforced. This allows a user with limited permissions to move an entry into a section where they lack write access, violating access control policies. The vulnerability affects versions starting from 5.0.0-RC1 up to but excluding 5.9.21. The flaw is classified under CWE-284 (Improper Access Control) and has a CVSS 4.0 base score of 6.0 (medium severity).
Potential Impact
An authenticated user with low privileges who can move entries can bypass section-level write restrictions by moving entries into sections where they only have read access. This undermines the CMS's authorization model, potentially allowing unauthorized content injection, interference with editorial boundaries, approval workflows, and section-specific business logic.
Mitigation Recommendations
This vulnerability has been fixed in Craft CMS version 5.9.21. Users should upgrade to version 5.9.21 or later to remediate this issue. No official patch or temporary fix is indicated beyond upgrading. Until upgraded, restrict entry move permissions to trusted users only.
