Apple Mail Lockdown Mode Remote Image Display Vulnerability

A logic vulnerability has been identified in Apple Mail's handling of remote images, specifically when replying to emails in Lockdown Mode. This issue is present in iOS 18.7.9, iPadOS 18.7.9, macOS Sequoia 15.7.7, macOS Sonoma 14.8.7, and macOS Tahoe 26.5. The vulnerability arises from inadequate checks, allowing remote images to be displayed in Mail while Lockdown Mode is active, which could potentially expose users to privacy risks.

Impact

Exploitation of this vulnerability could lead to unauthorized display of remote images in Apple Mail, bypassing Lockdown Mode's privacy protections.
