CVE-2026-14792Network attack vector

Email enumeration and PIN guessing via unthrottled actions

Published Jul 6, 2026 · Updated Jul 6, 2026

Improper access control in Formbricks 5.0.0 link-survey actions allows remote attackers to probe responses and repeatedly guess survey PINs. The isSurveyResponsePresentAction accepts arbitrary survey and email values without a feature guard or rate limit, while validateSurveyPinAction checks PIN guesses without throttling. A reachable link survey and its identifier are required; the actions expose response-presence results and permit repeated PIN attempts without authentication.
