Plesk — Vulnerabilities & Security Advisories 4

Plesk serves as a web hosting control panel enabling server management and website deployment. Historically, vulnerabilities have included remote code execution, cross-site scripting, and privilege escalation, often stemming from improper input validation or authentication flaws. The platform has faced security incidents, including a 2019 vulnerability (CVE-2019-6799) allowing unauthorized access to sensitive data. With four current CVEs, ongoing security concerns persist, particularly around default configurations and third-party component integration. Regular updates and hardening remain critical for secure deployment.
