CVE-2025-24172Network attack vector

Privacy disclosure via Mail preview sandbox bypass

Published Mar 31, 2025 · Updated Jun 18, 2026

Permissions error in macOS Mail before 13.7.5, 14.7.5, and 15.4 allows remote attackers to load blocked preview content. The Mail preview sandbox does not consistently enforce the Block All Remote Content permission, so some previews fetch external resources despite that setting. A crafted message that reaches a preview contacts a sender-controlled server; the request reveals preview activity and, when IP hiding is off, the Mac's network address.
