CVE-2026-126061 · Severity: medium · CVSS 4.3 · Published 2026-11-10

Winter CMS is a content management system built on Laravel. An authenticated backend user can access sensitive profile information of other users by enumerating user IDs through the MyAccount controller, exposing names, email addresses, roles, and group memberships without proper authorization checks. Password data is protected, but the exposure of account metadata could facilitate social engineering or targeted attacks against other administrators.

Technical details

The MyAccount controller in versions 1.2.13 inherits FormController actions (create, update, preview) with an empty $requiredPermissions array. The formFindModelObject() method resolves user identifiers through an unscoped Backend\Models\User query, allowing authenticated users to enumerate and read other users' profile attributes by crafting requests to /backend/myaccount/preview/{user_id}. Authorization guards prevent cross-user writes, but read access is not restricted.
