DescriptionCVE.org

A privacy issue was addressed with improved handling of temporary files. This issue is fixed in macOS Sequoia 15.7.4, macOS Tahoe 26.3. An app may be able to capture a user's screen.

AnalysisAI

A privacy vulnerability in macOS allows applications to capture a user's screen through improper handling of temporary files. The issue affects macOS Sequoia versions prior to 15.7.4 and macOS Tahoe versions prior to 26.3, enabling unauthorized screen capture by malicious or compromised applications. This vulnerability represents an information disclosure threat where sensitive user data visible on screen could be exfiltrated without user consent or awareness.

Technical ContextAI

The vulnerability stems from inadequate security controls around temporary file handling in macOS, which relates to CWE-based information disclosure through insecure temporary file management. The affected products are identified via CPE as Apple macOS across multiple versions (cpe:2.3:a:apple:macos:*:*:*:*:*:*:*:*), indicating the flaw exists in the core operating system's file system abstraction and screen capture mechanisms. The root cause involves temporary files used by the screen capture process or related APIs not being properly isolated or protected, allowing unprivileged applications to access or monitor these files to extract screen contents.

RemediationAI

Users should immediately update to macOS Sequoia 15.7.4 or macOS Tahoe 26.3 or later, as Apple has patched the underlying temporary file handling vulnerability in these releases. The patches are available through System Preferences > Software Update. Until systems can be updated, users should review and restrict application permissions in System Preferences > Security & Privacy, disable screen sharing and remote access features if not actively needed, and monitor installed applications for suspicious behavior. Additional mitigations include using privacy screen overlays for sensitive work and reviewing application permissions regularly.
