This permission bypass creates a clear path toward privilege escalation and potentially enables arbitrary code execution. The weakness corresponds to CWE-732 and is rated with a CVSS score of 9.8, indicating a critical severity level. The exploit probability, as reflected by an EPSS score of less than 1%, is low but nonzero, so while the likelihood of widespread exploitation is modest, the consequences are severe.", "risk_and_exploitability": "With a CVSS of 9.8 the vulnerability carries a critical rating, and although an EPSS score below 1% indicates rare use, the attack vector is likely local through the installation or execution of a privileged application.
