CVE-2025-43190 is a medium-severity Path Traversal (CWE-22) vulnerability in Apple Macos. Its CVSS base score is 5.5 (Medium).
Operationally, ranked at the 17th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Control response
Mitigating Controls (NIST 800-53 r5) AI
Directly requires validation of path inputs to reject malformed directory traversals that would otherwise allow an app to escape its sandbox and read sensitive user data.
Enforces the operating-system access-control policy on file-system objects so that even a malicious app cannot read files outside its authorized container.
Limits every app to the minimum set of file-system privileges needed for its function, thereby reducing the impact of any residual path-validation flaw.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Patching/maintenance can remediate known path-traversal flaws in deployed software (partial prevention of exploitability) but does nothing to stop the coding defect from being introduced in the first place.
PR.AA-05 defines and reviews access policies but does not address code-level pathname neutralization, so neither direction prevents CWE-22.

Security testing in development catches path traversal via static/dynamic analysis.
Secure SDLC mandates input validation and path sanitization that directly prevent path traversal.
Application security requirements include rules for safe file handling and canonicalization.
Secure architecture principles require least-privilege file access and directory isolation.
Secure coding standards explicitly forbid unsafe path construction and mandate safe APIs.
Information access restriction limits which files an application may read or write.
