Summary

CVE-2026-35371 is a low-severity User Interface (UI) Misrepresentation of Critical Information (CWE-451) vulnerability in Uutils Coreutils. Its CVSS base score is 3.3 (Low).

Operationally, ranked at the 2th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SI-2 (Flaw Remediation) and AC-16 (Security and Privacy Attributes) — see the control section below for these in your framework.

Vulnerability Data

The id utility in uutils coreutils exhibits incorrect behavior in its "pretty print" output when the real UID and effective UID differ. The implementation incorrectly uses the effective GID instead of the effective UID when performing a name lookup for…

the effective user. This results in misleading diagnostic output that can cause automated scripts or system administrators to make incorrect decisions regarding file permissions or access control.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires timely remediation of the code flaw in the id utility that produces incorrect UID output.

prevent

Ensures security attributes such as real/effective UIDs are correctly associated and represented rather than misreported.

detect

Verifies integrity of software output and detects when diagnostic information about UIDs has been corrupted or falsified.

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 address design and implementation of accurate, non-spoofable UI elements.

PR.AT-01 partial match
prevents

User awareness training helps people recognize and avoid harm from UI misrepresentation such as phishing, but does not prevent the flaw itself.

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.

detects

Security testing can detect UI misrepresentation vulnerabilities before deployment.

prevents

Security awareness training can teach users to recognize UI misrepresentation and phishing attempts.

mitigates

Web filtering can block known phishing sites that exploit UI misrepresentation.

prevents

Secure development lifecycle includes UI/UX security requirements that can prevent misrepresentation of critical information.

prevents

Application security requirements can mandate proper display and validation of critical information in the UI.

prevents

Secure coding practices can prevent UI flaws that obscure or spoof critical information.
