Improper access control in Formbricks 5.0.0 allows remote unauthenticated attackers to bypass authorization checks in the link survey handler, enabling unauthorized manipulation of survey data with limited integrity and availability impact. The flaw resides in the Survey Handler component (apps/web/modules/survey/link/actions.ts) and is tagged as an authentication bypass, confirmed by the CVSS 4.0 PR:N metric indicating no credentials are required. No active exploitation has been confirmed and no public exploit code has been identified; a patch is available as release candidate 5.1.0-rc.1.
