From Hacker News
And it's not actually that much information "about the security content". For example: "Impact: An app may be able to access sensitive user data. Description: An access issue was addressed with additional sandbox restrictions." This references CVE-2026-43819, which doesn't have any more information. Compare this with the nearly decade-old https://support.apple.com/en-gb/103680, and you see much more specific information about problems and their remedies (except in situations where Apple's action was to update a vendor component).
