CVE-2026-110620 Details
Description
Formbricks before 4.9.0 contains an authorization bypass vulnerability in server actions like resetSurveyAction and updateSegmentAction that fail to verify resource ownership against the supplied organizationId. Authenticated owners or managers of any organization can pair their own organization identifier with victim resource IDs to delete survey responses, modify segments and quotas, or alter pending invitations.
A vulnerability exists in Formbricks versions prior to 4.9.0, allowing authorization bypass in server actions such as 'resetSurveyAction' and 'updateSegmentAction'. These actions fail to properly verify resource ownership against the provided 'organizationId'. As a result, authenticated owners or managers can exploit this by using their own organization identifier to manipulate resources belonging to other organizations. This includes deleting survey responses, modifying segments and quotas, or changing the status of pending invitations.
Users can update to Formbricks version 4.9.0 or later, where this vulnerability has been fixed.
