The advisory states that an access issue was addressed by adding sandbox restrictions in macOS Sequoia 15.7.2 and macOS Tahoe 26. The issue could allow an application to read sensitive user data; the description indicates that this is an access control problem rather than a code execution flaw.

Apple macOS users running versions older than Sequoia 15.7.2 or Tahoe 26 are potentially vulnerable. The vulnerability was fixed in those releases, so any installations before those versions may be affected.

The CVSS score of 5.5 classifies the risk as moderate. The EPSS score of less than 1% suggests a low probability of exploitation at this time. This vulnerability is not listed in the CISA KEV catalog. The advisory does not specify the attack vector; it only notes that sandbox restrictions were added. The context implies that the issue relates to applications running on the affected Mac, but the precise exploitation method is not detailed in the advisory.
