Critical Vulnerabilities Uncovered in Open Source CasaOS Cloud Software


Two severe security issues discovered in the open-source CasaOS personal cloud software could allow attackers to gain arbitrary code execution and take control of vulnerable systems. The vulnerabilities, CVE-2023-37265 and CVE-2023-37266, both have a CVSS score of 9.8 out of a possible 10.
