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: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

CVE published 4 Nov 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

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 26 Oct 2026.

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 or the CVSS exploit maturity 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

Organizations should promptly update affected macOS systems to versions Sequoia 15.7.2 or Tahoe 26.1 or later, where the vulnerability has been addressed with improved access control checks. Beyond patching, organizations should enforce strict application whitelisting and monitor for unusual application behavior that could indicate sandbox escape attempts. Employ endpoint detection and response (EDR) solutions capable of detecting privilege escalation and sandbox breakout patterns. Limit local user privileges to the minimum necessary to reduce the risk of exploitation by low-privilege accounts. Regularly audit installed applications and remove or restrict those that are unnecessary or untrusted. Implement network segmentation to contain potential lateral movement if a sandbox escape occurs. Additionally, educate users about the risks of installing untrusted software and maintain robust backup and recovery procedures to mitigate potential damage from exploitation. Finally, monitor security advisories from Apple and threat intelligence sources for any emerging exploit activity related to this vulnerability.

Description

This issue was addressed with improved checks. This issue is fixed in macOS Sequoia 15.7.2, macOS Tahoe 26.1. An app may be able to break out of its sandbox.

Impact

The primary impact of CVE-2025-43481 is the potential compromise of confidentiality and integrity within affected macOS systems. By escaping the sandbox, a malicious or compromised application can access files, processes, or system resources that should be restricted, leading to unauthorized data access or modification. This can facilitate privilege escalation, lateral movement within the system, or the deployment of further malicious payloads. For organizations, this undermines the trust model of application isolation, increasing the risk of data breaches, intellectual property theft, and system manipulation. Although availability is not directly impacted, the breach of sandbox boundaries can lead to broader system compromises that may eventually affect system stability or availability. The risk is particularly acute in environments where macOS is used for sensitive operations, including software development, creative industries, and enterprise environments with confidential data. The lack of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits following public disclosure.

Pillar weaknessCWE Top 25 (2025): #19OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.
MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
Architecture and Design · Operation
Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
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.
