How the CVE Works:
CVE-2025-30460 is a macOS permissions flaw allowing apps to bypass sandbox restrictions and access protected user data. The vulnerability stems from improper validation of app enments, enabling malicious applications to escalate privileges or read sensitive files without authorization. Apple addressed this by removing vulnerable code segments and enforcing stricter enment checks in macOS Ventura 13.7.5, Sequoia 15.4, and Sonoma 14.7.5. The exploit leverages API misconfigurations to intercept system calls, granting unintended access to directories like `~/Library/Application Support` or keychain items.
DailyCVE Form:

What Undercode Say:
Analytics:
- CVSS 4.0 Score: 9.1 (AV:L/AC:L/AT:N/PR:N/UI:N/S:C/C:H/I:H/A:N)
- Attack Vector: Local
- Exploitability: Low complexity
Exploit Commands:
1. List vulnerable enments:
codesign -d --enments - /Applications/Malicious.app
2. Check sandbox violations:
log stream --predicate 'eventMessage contains "sandbox" AND process == "Malicious"'
Protection Code:
1. Verify app enments:
SecRequirementCreateWithString("enment[bash] = true", nil, &requirement)
2. Enforce file restrictions:
santactl rule --path /Users/Shared --block --identifier "CVE-2025-30460_MITIGATION"
Mitigation Steps:
- Update to patched macOS versions immediately.
- Revoke unnecessary enments via Xcode:
<dict> <key>com.apple.security.app-sandbox</key> <true/> </dict>
- Monitor `tccd` logs for data access attempts:
log show --predicate 'subsystem == "com.apple.TCC"' --last 24h
