Summary

CVE-2026-43698 is a high-severity Argument Injection (CWE-88) vulnerability in Apple Macos. Its CVSS base score is 7.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked at the 10th 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 SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing can discover argument-injection flaws in command-construction code but does not stop their introduction.

SI-10 Information Input Validation good match

Input validation directly stops construction of command strings containing unneutralized delimiters or injected arguments.

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.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require proper input validation and command construction to prevent argument injection.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing can detect argument injection but does not prevent it at the source.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle mandates input validation and command construction practices that directly prevent argument injection.

A.8.26 Application security requirements partial match
prevents

Application security requirements include explicit rules for safe command-line argument handling and escaping.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure architecture principles discourage unsafe command invocation patterns and favor safer APIs.

A.8.28 Secure coding partial match
prevents

Secure coding standards explicitly require proper neutralization of command arguments, directly eliminating CWE-88.
