Processing a maliciously crafted image may lead to disclosure of user information.
The vulnerability has a CVSS score of 5.5, classified as medium severity. The attack vector is local, and the attack complexity is low, requiring no privileges but necessitating user interaction. The confidentiality impact is high, while the integrity and availability impacts are none.
Technical Analysis
The root cause of this vulnerability lies in insufficient bounds checks when processing images. This inadequate validation can allow attackers to manipulate image data, which could lead to unauthorized disclosure of sensitive information. The attack vector is local, meaning that an attacker must have access to the local environment to exploit this vulnerability.
The attack complexity is classified as low, indicating that exploiting this vulnerability is straightforward for an attacker. No special privileges are required, but user interaction is necessary, as victims need to open or process the malicious image. The confidentiality impact is assessed as high due to the potential for sensitive information exposure, while integrity and availability impacts are rated as none.
Risk & Impact Analysis
The real-world risk of this vulnerability is significant, particularly for organizations utilizing Apple products across their operations. The potential for unauthorized disclosure of sensitive user information poses a serious threat, especially in environments where personal data is handled. Organizations should address this vulnerability in their priority patch cycle.
The vulnerability has been assessed with a CVSS score of 5.5, indicating a medium level of severity. Given the high confidentiality impact, organizations must act quickly to mitigate the risk. The urgency for remediation is moderate, and organizations should schedule remediation as part of their regular maintenance processes.

|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The affected versions include iOS 18.7.5 and iPadOS 18.7.5, and all versions prior to vendor patch for macOS, tvOS, visionOS, and watchOS. Specifically, versions of macOS prior to 14.8.4 and all versions of iOS prior to 26.3 are vulnerable. Users should ensure their systems are updated to the latest versions.
Mitigation & Remediation
Organizations should prioritize patching immediately. The latest updates are available for iOS, iPadOS, macOS, tvOS, visionOS, and watchOS. Users should upgrade to iOS 18.7.5, iPadOS 18.7.5, macOS Sequoia 15.7.4, macOS Sonoma 14.8.4, tvOS 26.3, visionOS 26.3, and watchOS 26.3 to mitigate the risk.
In the absence of immediate patch availability, organizations should consider implementing configuration hardening strategies. This includes restricting access to image processing applications and ensuring that users are educated about potential risks associated with processing untrusted images.
Monitoring systems for unusual access patterns or image processing anomalies is also recommended to detect any attempts to exploit this vulnerability.
Detection Guidance
To detect potential exploitation attempts, organizations should monitor logs for unusual image processing activities. Indicators may include unexpected access to image files or strange behavior in applications handling images. Security teams should establish behavioral baselines to identify anomalies.
Additionally, network signatures can be implemented to identify suspicious image payloads that may indicate an attempt to exploit the vulnerability.
