CVE-2026-91216

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

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

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

Extends the same authentication requirement to non-organizational users accessing critical functionality.

Requires authentication of services before they can invoke or expose critical functions.

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

Ongoing audits and performance reviews of suppliers detect and correct situations where access controls or privilege assignments are weaker than contractually required, limiting an attacker's ability to exploit improper access control in the supplier's environment.

Explicitly assigning which party manages each access-control mechanism and requiring the provider to enforce the customer's access requirements reduces the chance that authorization decisions are omitted or left to default permissive settings.

Formal incident containment and post-incident root-cause analysis reduce the window during which improper access control flaws can be exploited and ensure discovered authorization weaknesses are corrected.

Establishing explicit responsibilities and controls for PII processing limits situations where access control mechanisms fail to restrict who can view or manipulate personal data.
