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.
