These vulnerabilities, if exploited, could allow an attacker to perform a range of malicious activities, including SQL injection attacks, denial-of-service (DoS) attacks, bypassing security measures, disclosing sensitive information, and ultimately executing arbitrary program code with administrator privileges. Successful exploitation poses a significant risk to the confidentiality, integrity, and availability of systems managed by Fleet. Defenders should prioritize patching and implementing detection measures to mitigate the risk associated with these vulnerabilities.
