The impact is that a malicious or compromised application could read data that a user expects to remain protected, potentially exposing personal information or sensitive information stored on the device.", "risk_and_exploitability": "The CVSS score of 5.5 indicates a medium level of severity. EPSS shows less than 1 percent likelihood of exploitation, and the vulnerability is not listed in the CISA KEV catalog.
