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

Attack Vector: Physical: The attack requires the attacker to physically touch or manipulate the vulnerable component. Physical interaction may be brief or persistent.
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: 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-2024-40813, organizations and users should immediately update all affected Apple devices to iOS 17.6, iPadOS 17.6, or watchOS 10.6 or later, where the vulnerability is patched. Beyond patching, enforce strict physical security controls to prevent unauthorized access to devices, including secure storage, device tracking, and policies for lost or stolen devices. Disable Siri access from the lock screen if not essential, reducing the attack surface by preventing voice assistant invocation without authentication. Implement mobile device management (MDM) solutions to enforce security policies, including disabling lock screen features that expose sensitive data. Educate users about the risks of physical device access and encourage the use of strong passcodes or biometric authentication to further protect device access. Regularly audit device configurations to ensure compliance with security best practices. For high-security environments, consider additional controls such as remote wipe capabilities and monitoring for unusual device activity. These combined measures will reduce the likelihood of exploitation and limit data exposure if physical access is gained.

Description

A lock screen issue was addressed with improved state management. This issue is fixed in iOS 17.6 and iPadOS 17.6, watchOS 10.6. An attacker with physical access may be able to use Siri to access sensitive user data.

Impact

The primary impact of CVE-2024-40813 is the unauthorized disclosure of sensitive user data through Siri on locked Apple devices. This compromises confidentiality but does not affect data integrity or system availability. Organizations relying on Apple devices for sensitive communications or data storage face risks if devices are physically accessed by unauthorized individuals, such as in cases of theft or loss. Attackers could extract personal information, contacts, or other data accessible via Siri, potentially leading to privacy violations, social engineering, or further targeted attacks. While the vulnerability requires physical access, environments with high device turnover, shared devices, or insufficient physical security controls are particularly vulnerable. The lack of known exploits in the wild reduces immediate risk but does not eliminate the threat, especially as attackers may develop techniques to leverage this flaw. For enterprises, this vulnerability could undermine trust in device security and complicate compliance with data protection regulations if sensitive data is exposed. The medium severity rating reflects a moderate risk profile, emphasizing the need for prompt patching and physical security measures to mitigate potential data leakage.
