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.

Detectable: no evidence on record.

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.

What to do

Upgrade iOS and iPadOS to 26.3 or 18.7.5; macOS to 26.3, 15.7.4 or 14.8.4.

AI-suggested

Apply the latest Apple security updates immediately: update iOS and iPadOS devices to version 18.7.5 or later, and macOS devices to the corresponding patched versions (Sequoia 15.7.4, Sonoma 14.8.4, Tahoe 26.3).
Enforce strict app installation policies, limiting installation to trusted sources such as the official Apple App Store and vetted enterprise apps.
Use Mobile Device Management (MDM) solutions to control app permissions and monitor installed applications for suspicious behavior.
Educate users about the risks of installing untrusted apps and encourage regular OS updates.
Implement runtime application self-protection (RASP) or endpoint detection solutions capable of detecting anomalous app behaviors indicative of attempts to access unauthorized data.
For high-security environments, consider restricting or disabling app state sharing features where feasible until patches are applied.
Monitor device logs and network traffic for unusual data access patterns that could indicate exploitation attempts. These steps go beyond generic advice by focusing on controlling app sources, leveraging management tools, and monitoring for exploitation indicators.

Description

The issue was addressed with additional restrictions on the observability of app states. This issue is fixed in iOS 18.7.5 and iPadOS 18.7.5, iOS 26.3 and iPadOS 26.3, macOS Sequoia 15.7.4, macOS Sonoma 14.8.4, macOS Tahoe 26.3. A sandboxed app may be able to access sensitive user data.

Impact

The primary impact of CVE-2026-20680 is the unauthorized disclosure of sensitive user data from sandboxed applications on Apple iOS and iPadOS devices. This can lead to privacy violations, exposure of personal or corporate confidential information, and potential data leakage. Since the vulnerability does not affect integrity or availability, it does not allow modification or disruption of system functions but compromises confidentiality significantly. Organizations using Apple mobile devices, especially those with BYOD policies or allowing third-party app installations, face increased risk of data breaches if malicious apps exploit this flaw. The local attack vector and low privilege requirement mean that any app installed on the device could potentially exploit this vulnerability without needing user interaction, increasing the risk in environments with less stringent app vetting. This could affect enterprises, government agencies, and individuals relying on iOS/iPadOS for sensitive communications or data storage. The absence of known exploits in the wild reduces immediate risk but does not eliminate the threat, making timely patching critical.

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.
