The flaw allows a malicious application to bypass authorization controls and read protected user data, representing a significant confidentiality compromise. The weakness is classified as CWE\u2011290, indicating an authorization bypass through a user\u2011controlled key.", "risk_and_exploitability": "The CVSS score of 9.8 indicates a critical severity. The EPSS score of < 1% suggests a low likelihood of exploitation at the moment. The vulnerability is not listed in CISA's KEV catalog. The likely attack vector involves an attacker delivering a downgraded or improperly signed application that passes code\u2011signing checks and then accessing protected user data. There are no known public exploits, but the high severity warrants immediate attention.
