CVE-2026-57131

Explicitly identifies and limits actions permitted without authentication, preventing critical functions from being exposed.

AC-24 mandates that access control decisions are applied to each request, preventing bypass of authorization logic.

AC-25 requires a tamperproof, always-invoked reference monitor that ensures authorization checks cannot be omitted.

Access enforcement requires prior authentication before any authorization decision for critical functions.

Least privilege limits the damage an injected code fragment can perform once executed.

Directly mandates unique identification and authentication of users before access to functions requiring identity.

Managing identities and credentials is a prerequisite for authentication but does not itself enforce it on critical functions.

Directly requires authentication of users/services/hardware, which eliminates missing authentication for critical functions.

Defining and enforcing authorizations assumes prior authentication and therefore only partially mitigates the absence of authentication.

Protecting networks from unauthorized access can be undermined by missing authentication but does not address the root authentication gap.

Requiring formal authorization of every access request before rights are granted ensures that checks for required permissions are performed, preventing missing authorization checks from being introduced.

Mandatory authorization checks and central records of granted rights ensure that every access attempt is preceded by an explicit decision rather than relying on missing checks.

Segregating the approval of access rights from their implementation provides an independent check that reduces the impact of missing authorization checks in the resulting system configuration.

By requiring competent outsiders to verify that every function enforces the need-to-know principle, the control lowers the likelihood that missing authorization checks persist undetected.

Mandating authentication requirements for critical functions at the requirements-gathering stage ensures that essential operations are not left unprotected by missing login or verification mechanisms.

Requiring authentication of systems and restricting which devices may join the network prevents missing-authorization flaws from being exploitable across network boundaries.
