What is CVE-2026-129153?

SurveyKing versions 1.12.0 to 1.13.2 are susceptible to an authorization bypass issue in their linked survey feature. This vulnerability allows authenticated attackers to exploit the system by referencing an incorrect linkSurveyId, which does not belong to their own project.
