Reservation Diary — Vulnerabilities & Security Advisories 6

Reservation Diary is a reservation management system primarily used by hospitality businesses to handle bookings and customer data. Historically, it has been susceptible to multiple remote code execution vulnerabilities, cross-site scripting flaws, and privilege escalation issues, with six CVEs documented to date. The application's web interface often contains insufficient input validation, leading to potential unauthorized access or system compromise. While no major public security incidents have been widely reported, the consistent pattern of vulnerabilities in older versions suggests a need for regular security updates and careful configuration to mitigate risks.
