wintercms — Vulnerabilities & Security Advisories 18

WinterCMS serves as a flexible PHP content management system for building websites and applications. Historically, it has been susceptible to multiple remote code execution vulnerabilities, cross-site scripting flaws, and privilege escalation issues, accounting for its nine recorded CVEs. The platform's modular architecture introduces potential attack surfaces through plugins and themes. While no major public security incidents have been widely documented, the consistent pattern of vulnerabilities suggests developers should implement strict input validation, principle of least privilege configurations, and keep the system updated to mitigate risks associated with its historically vulnerable components.
