# CVE-2026-129152: SurveyKing 1.12.0 through 1.13.2 Authentication Bypass via saveAnswer Response Submission

Status: published. Published: 2026-11-13. Updated: 2026-11-13.

SurveyKing 1.12.0 through 1.13.2 contains an authentication bypass vulnerability that allows unauthenticated attackers to submit survey responses because AnswerServiceImpl.saveAnswer skips login-required and survey password checks. Attackers can submit responses to protected surveys and set createBy in the request body to impersonate other users, corrupting survey results.
