AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N
Local malicious app (AV:L) needs the user to run it (UI:R); no prior privilege (PR:N); flaw only discloses restricted files, so C:H, I:N, A:N.

An input validation issue was addressed with improved input validation. This issue is fixed in macOS Golden Gate 27, macOS Sequoia 15.8, macOS Tahoe 26.7. An application may be able to access restricted files.
AnalysisAI
A path-validation weakness in Apple macOS lets a malicious application read files outside its permitted scope, exposing restricted data to an app that should not be able to reach it. Exploitation requires local conditions: the attacker must deliver a crafted application to the Mac and convince the user to launch it (CVSS:3.1/AV:L/AC:L/PR:N/UI:R), after which the app can achieve high confidentiality impact but cannot modify data or cause a denial of service. …

Vulnerability AssessmentAI
| Exploitation | Requires local execution of attacker-controlled code: the attacker must get a malicious or crafted application onto the Mac and have the user run it (UI:R). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a moderate-severity local information-disclosure flaw, not an urgent priority. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the vendor-released patch: upgrade to macOS Tahoe 26.7, macOS Sequoia 15.8, or macOS Golden Gate 27, which contain the improved input validation that closes the traversal (see Apple advisories https://support.apple.com/en-us/149035, https://support.apple.com/en-us/149042, and https://support.apple.com/en-us/149043). … Detailed patch versions, workarounds, and compensating controls in full report. |
