Limesurvey — Vulnerabilities & Security Advisories 6

LimeSurvey is an open-source survey tool used for collecting data through customizable forms and questionnaires. Historically, it has faced vulnerabilities including remote code execution, cross-site scripting, and privilege escalation, often stemming from improper input validation and access control flaws. The platform has accumulated six CVEs, with some issues allowing attackers to execute arbitrary code or bypass authentication. While no major public security incidents have been widely documented, the consistent presence of vulnerabilities in areas like file handling and session management suggests potential risks for organizations deploying the software without hardening. Regular updates and proper configuration remain critical for maintaining security.
