Confidentiality: High
Integrity: None
Availability: None

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Local: The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either: the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 31 Mar 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-25.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

To mitigate CVE-2025-30451, organizations and users should promptly update all macOS devices to version Sequoia 15.4 or later, where the vulnerability has been fixed. Beyond patching, organizations should enforce strict application installation policies, allowing only trusted and vetted applications to run on macOS systems to reduce the risk of malicious apps exploiting this vulnerability. Implementing endpoint protection solutions that monitor for unusual app behavior or attempts to access sensitive data can provide additional defense-in-depth. User education is important to prevent inadvertent installation or execution of untrusted applications. For environments with high security requirements, consider restricting local user permissions to limit the ability to install or run unauthorized software. Regular audits of installed applications and system logs can help detect suspicious activity related to sensitive data access. Finally, organizations should maintain an up-to-date inventory of macOS devices and ensure timely deployment of security updates.

Description

This issue was addressed with improved redaction of sensitive information. This issue is fixed in macOS Sequoia 15.4. An app may be able to access sensitive user data.

Impact

The primary impact of CVE-2025-30451 is the unauthorized disclosure of sensitive user data on affected macOS systems. This can lead to privacy violations, leakage of personal or corporate confidential information, and potential further exploitation if the leaked data includes credentials or other sensitive tokens. Since the vulnerability requires local access and user interaction, remote exploitation is not feasible, limiting the attack surface. However, in environments where users may install untrusted applications or where insider threats exist, the risk is significant. The confidentiality breach can undermine trust in macOS devices, especially in enterprise or government settings where sensitive data protection is critical. There is no impact on system integrity or availability, so the threat does not cause system corruption or denial of service. Organizations relying heavily on macOS for sensitive workloads or data storage are at higher risk, particularly if patching is delayed. The absence of known exploits in the wild reduces immediate risk but does not eliminate the potential for future exploitation.

Architecture and Design · Separation of Privilege
Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
