User Interaction: None
Scope: Unchanged
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: 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.

Exploitation evidence

Disclosed: evidence found.
CVE published 16 Sep 2024
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
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
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 2026-10-26.

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-2024-40844, organizations and users should promptly update all affected Apple devices to the patched versions: iOS 17.7, iPadOS 17.7, macOS Sequoia 15, macOS Sonoma 14.7, and macOS Ventura 13.7. Beyond patching, organizations should enforce strict app installation policies to prevent unauthorized or untrusted apps from being installed, reducing the risk of local exploitation. Employ mobile device management (MDM) solutions to monitor and control app permissions, especially those that can access local files or run background processes. Educate users about the risks of installing apps from unverified sources and the importance of device physical security to prevent local access attacks. Additionally, review and limit the use of Shortcuts workflows that handle highly sensitive data to minimize exposure. Regularly audit device security configurations and monitor for unusual app behaviors that could indicate exploitation attempts.

Description

A privacy issue was addressed with improved handling of temporary files. This issue is fixed in iOS 17.7 and iPadOS 17.7, macOS Sequoia 15, macOS Sonoma 14.7, macOS Ventura 13.7. An app may be able to observe data displayed to the user by Shortcuts.

Impact

The primary impact of CVE-2024-40844 is the unauthorized disclosure of sensitive data displayed by the Shortcuts app on affected Apple devices. This can lead to privacy breaches where malicious or compromised apps can silently observe confidential information without user consent or awareness. For organizations, this could mean leakage of sensitive operational data, personal information, or credentials if such data is processed or displayed via Shortcuts workflows. Although the vulnerability does not affect system integrity or availability, the confidentiality breach can undermine trust in Apple platforms and potentially facilitate further targeted attacks or espionage. The requirement for local access and low privileges limits remote exploitation but does not eliminate risk, especially in environments where devices may be physically accessed or compromised by malware. The lack of known exploits in the wild reduces immediate risk but does not preclude future exploitation attempts.
