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: 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.

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

To mitigate CVE-2025-43382, organizations should immediately deploy the security updates released by Apple for macOS Sequoia 15.7.2, Sonoma 14.8.2, and Tahoe 26.1 or later. Beyond patching, organizations should enforce strict application control policies to limit the installation and execution of untrusted or unnecessary applications, reducing the risk of local exploitation. Employ endpoint detection and response (EDR) solutions to monitor for suspicious local activity indicative of attempts to access unauthorized directories. Regularly audit user permissions and restrict local user privileges to the minimum necessary to reduce the attack surface. Educate users about the risks of installing unknown software and maintain robust backup procedures to protect sensitive data. For environments with high security requirements, consider implementing macOS security features such as System Integrity Protection (SIP) and sandboxing to further limit application capabilities. Finally, maintain an inventory of macOS devices and ensure timely patch management processes are in place to address vulnerabilities promptly.

Description

A parsing issue in the handling of directory paths was addressed with improved path validation. This issue is fixed in macOS Sequoia 15.7.2, macOS Sonoma 14.8.2, macOS Tahoe 26.1. An app may be able to access sensitive user data.

Impact

The primary impact of CVE-2025-43382 is unauthorized disclosure of sensitive user data on affected macOS systems. Since the vulnerability allows local applications with low privileges to bypass directory restrictions, attackers who gain limited access to a system could escalate their ability to gather confidential information, such as personal files, credentials, or other sensitive data stored in user directories. This can lead to privacy violations, intellectual property theft, or facilitate further attacks like privilege escalation or lateral movement within a network. Although the vulnerability does not affect system integrity or availability, the exposure of sensitive data can have significant consequences for individuals and organizations, including regulatory compliance issues and reputational damage. The requirement for local access limits remote exploitation, but insider threats or malware already present on a device could exploit this flaw. Organizations relying heavily on macOS devices, especially in sectors handling sensitive data such as finance, healthcare, or government, face increased risk if patches are not applied promptly.

Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #6OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
Architecture and Design
For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks…
Implementation · Input Validation
Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174).
