CVE-2025-30456
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA parsing issue in the handling of directory paths was addressed with improved path validation. This issue is fixed in iOS 18.4 and iPadOS 18.4, macOS Sequoia 15.4, macOS Sonoma 14.7.5, macOS Ventura 13.7.5. An app may be able to gain root privileges.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA path validation vulnerability in Apple operating systems allows a malicious application to bypass directory path validation, potentially enabling privilege escalation to root. The fix involves improved path validation logic in the affected OS components.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check iOS version on iPhoneGo to Settings > General > About and look at the 'Version' fieldAffected if Version number is less than 18.4 (e.g., 18.3.x, 18.2.x, etc.)
-
Check iPadOS version on iPadGo to Settings > General > About and look at the 'Version' fieldAffected if Version number is less than 18.4 (e.g., 18.3.x, 18.2.x, etc.)
-
Check macOS versionClick Apple menu > About This Mac and note the version number under macOS nameAffected if Version is 13.x below 13.7.5, or 14.x below 14.7.5, or 15.x below 15.4
You are affected if your device runs iOS/iPadOS below 18.4, or macOS Ventura below 13.7.5, macOS Sonoma below 14.7.5, or macOS Sequoia below 15.4.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
