Parallels — Vulnerabilities & Security Advisories 84

Parallels Desktop and Server provide virtualization solutions for macOS and Windows, enabling users to run multiple operating systems simultaneously on a single host. With eighty recorded Common Vulnerabilities and Exposures, the software has historically been susceptible to remote code execution, cross-site scripting, and privilege escalation flaws. These vulnerabilities often stem from improper input validation within the virtual machine communication channels or hypervisor components, allowing attackers to potentially escape the sandbox environment or execute arbitrary code with elevated privileges. While no catastrophic, widespread breaches have defined its public history, the high volume of CVEs indicates persistent security challenges in its core architecture. Users are advised to maintain strict patch management protocols to mitigate risks associated with these known defects, ensuring that the virtualization layer remains isolated from potential host compromise.
