Sensitive file disclosure via unchecked attachment paths

Published May 11, 2026 · Updated May 11, 2026

WebKit in affected Safari, iOS, iPadOS, macOS, and visionOS releases allows remote attackers to disclose sensitive files via web content. WebProcessProxy accepted paths from RegisterAttachmentIdentifierFromFilePath without checking whether pasteboard or drag-and-drop operations had authorized them. Attachment elements must be enabled and malicious web content must submit a local path; access remains bounded by files available to the process.
