CVE intelligence and bounded remediation

CVE-2026-50280 — Craft CMS is a content management system (CMS)

Medium CVSS 6

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.

Matched remediation archetype

Authorization bypass, IDOR, and cross-tenant access

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map object and action authorization checks across API, UI, batch, import/export, and background-job paths.
  • Identify tenant, ownership, role, and policy boundaries for affected resources and administrative operations.
  • Use synthetic fixtures to compare intended access matrices without accessing another user's real data.

Remediate safely

  • Enforce server-side authorization at each resource access and state transition using the authenticated principal and trusted tenant context.
  • Scope data queries by tenant and ownership; treat client-supplied identifiers, roles, and policy claims as untrusted.
  • Add deny-by-default policy tests for horizontal and vertical access across every affected transport.
