The flaw is a form of improper access control that could lead to confidential data being read by an unauthorized app. As a result, user privacy is directly impacted, with the potential for personal data to be disclosed to a malicious or unintended application.", "risk_and_exploitability": "The CVSS score of 5.3 indicates a medium severity, and the EPSS score of less than 1% suggests a low likelihood of exploitation at this time. The vulnerability is not listed in the CISA KEV catalog, further indicating limited real-world exploitation.

The exploit requires no special user interaction beyond normal application use, but it is limited to platforms with the affected macOS versions.
