User Interaction: Required
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: 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: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
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 27 Jan 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

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 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

Update all Apple devices to the latest patched versions: iOS 18.3, iPadOS 18.3, iPadOS 17.7.4, macOS Sequoia 15.3, visionOS 2.3, and watchOS 11.3 as soon as possible.
Restrict installation of apps to trusted sources only, such as the official Apple App Store, to reduce the risk of malicious apps exploiting this vulnerability.
Implement Mobile Device Management (MDM) policies that limit app permissions and monitor app behavior for suspicious fingerprinting activities.
Educate users about the risks of installing untrusted or unknown apps and the importance of applying system updates promptly.
Use privacy-enhancing settings and tools available in iOS/iPadOS to limit data sharing and tracking where possible.
Monitor network traffic and device logs for unusual patterns that may indicate fingerprinting or tracking attempts.
For organizations, conduct regular privacy impact assessments and ensure compliance with relevant data protection regulations to mitigate legal risks associated with user tracking.

Description

This issue was addressed with improved redaction of sensitive information. This issue is fixed in iOS 18.3 and iPadOS 18.3, iPadOS 17.7.4, macOS Sequoia 15.3, visionOS 2.3, watchOS 11.3. An app may be able to fingerprint the user.

Impact

The primary impact of CVE-2025-24117 is on user privacy and confidentiality. By enabling apps to fingerprint users, attackers can track user behavior across apps and sessions without consent, potentially leading to profiling, targeted advertising, or more invasive privacy violations. For organizations, this can translate into compliance risks with privacy regulations such as GDPR or CCPA if user data is collected or processed without proper consent. Although the vulnerability does not directly compromise system integrity or availability, the erosion of user trust and potential regulatory penalties can have significant reputational and financial consequences. Enterprises deploying iOS and iPadOS devices, especially in sectors handling sensitive or regulated data (e.g., healthcare, finance), may face increased risk if users install untrusted apps. The requirement for user interaction and local app installation limits the scope somewhat, but the widespread use of Apple devices globally means the potential attack surface remains large. The vulnerability also underscores the need for vigilance against privacy-invasive techniques that do not rely on traditional exploit chains but rather on subtle data leakage.
