CVE-2026-43732Network attack vector

Sensitive information disclosure via improper path validation

Published Jun 29, 2026 · Updated Jun 29, 2026

Path traversal in WebKit in Apple Safari, iOS and iPadOS, and macOS before 26.5.2 allows remote attackers to disclose sensitive data. WebKit improperly validates paths while processing attacker-controlled web content, permitting access beyond an intended path boundary; Apple has not disclosed the affected function or data source. Exploitation requires a user to process malicious web content, and the published impact is limited to confidentiality with no reported modification or service interruption.
