Attack Vector: Physical
Attack Complexity: Low
Privileges Required: None
User Interaction: None
Scope: Unchanged
Confidentiality: Low
Integrity: None
Availability: None

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: 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: 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 Jan 2026
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.

What to do

Upgrade Apple iOS and iPadOS to 18.1.

AI-suggested

To mitigate CVE-2024-54556, organizations and users should promptly update all affected Apple devices to iOS and iPadOS version 18.1 or later, where the vulnerability has been addressed through improved state management. Additionally, users should configure their devices to minimize sensitive information displayed on the lock screen by disabling lock screen notifications or setting them to hide content until authentication. Enforcing strong device passcodes and enabling biometric authentication can further reduce risk. For enterprise environments, Mobile Device Management (MDM) solutions should be used to enforce lock screen notification policies and ensure timely OS updates. Physical security controls to prevent unauthorized access to devices are also critical. Monitoring for lost or stolen devices and implementing remote wipe capabilities can help mitigate potential data exposure. Finally, educating users about the risks of leaving devices unattended and the importance of applying updates is essential.

Description

This issue was addressed through improved state management. This issue is fixed in iOS 18.1 and iPadOS 18.1. A user may be able to view restricted content from the lock screen.

Impact

The primary impact of CVE-2024-54556 is a confidentiality breach, allowing unauthorized viewing of restricted content from the lock screen without authentication. This could lead to exposure of sensitive personal or corporate information, such as message previews, emails, calendar events, or other notifications that appear on the lock screen. While the vulnerability does not allow modification or deletion of data (no integrity or availability impact), the leakage of sensitive information can facilitate social engineering attacks, identity theft, or unauthorized data disclosure. Organizations with employees using Apple mobile devices may face increased risk of data leakage if devices are lost or stolen. The impact is mitigated by the requirement for physical access to the device, limiting remote exploitation. However, in high-security environments or where devices are frequently unattended, the risk is more pronounced. The absence of known exploits in the wild reduces immediate threat but does not eliminate the risk of future exploitation.

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.
