Summary
CVE-2025-24204 is a critical-severity Exposure of Sensitive Information to an Unauthorized Actor (CWE-200) vulnerability in Apple Macos. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 17% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and AC-4 (Information Flow Enforcement) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-24204 is a vulnerability affecting macOS Sequoia versions prior to 15.4, where an app may be able to access protected user data. The issue stems from insufficient checks and is classified under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor). It received a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating critical severity due to its high impact on confidentiality, integrity, and availability.
Attackers can exploit this vulnerability remotely over the network with low attack complexity, requiring no user privileges or interaction and without changing the scope of impact. A malicious app could leverage this flaw to read sensitive user data, potentially leading to unauthorized disclosure, modification, or disruption of system resources.
Apple addressed the vulnerability with improved checks in macOS Sequoia 15.4. Security practitioners should advise users to update to this version immediately. Additional details are available in Apple's security advisory at https://support.apple.com/en-us/122373 and the Full Disclosure mailing list posting at http://seclists.org/fulldisclosure/2025/Apr/8.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Access enforcement directly stops unauthorized actors from obtaining sensitive information.
Information flow enforcement structurally prevents sensitive data from reaching unauthorized recipients.
Protection of information at rest prevents unauthorized exposure of stored sensitive data.
Transmission confidentiality mechanisms stop exposure of sensitive data on the wire.
Least privilege reduces the set of actors who can reach sensitive information.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Suppressing system details, error specifics, and previous log-on information until successful authentication reduces the information an unauthenticated attacker can gather.
Requiring encryption, access controls, and recipient authentication for transfers directly reduces the chance that sensitive data reaches an unauthorized observer.
Secure delivery, protected storage, and confidentiality of allocation records limit exposure of authentication material to unauthorized observers.
A.8.1's policy+enforcement on access controls, storage encryption, malware protection, device registration, remote wipe/lock, physical/logical protections, partitioning, and BYOD separation (plus config enforcement via 8.9) stops most unauthorized exposure of sensitive data from endpoints; named remainder is exposures via error messages, side channels or non-endpoint vectors (see A.8.3 mostly on same CWE).
A.8.10 mandates timely, secure deletion (overwriting, crypto erase, certified disposal, automation per retention policy) of unneeded sensitive information on all media, which directly stops most exposure paths in CWE-200; the bounded remainder is exposure that is not a retention issue at all (e.g. CWE-209 error messages, CWE-203 observable discrepancies, CWE-215 debug code).
data masking (incl. pseudonymization/anonymization) directly limits exposure of sensitive data to unauthorized actors per the purpose and guidance, covering most but not all vectors in CWE-200 (e.g. residual indirect re-identification risks or non-masked exposure paths like error messages remain nameable)
Hardening callouts derived
DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.
