CVE-2026-90787

Binding security attributes to subjects/objects supplies the mechanism needed to track and enforce privileges correctly.

Account management defines and authorizes the exact privileges granted to each account or role.

Requiring explicit access-control decisions ensures privileges are evaluated rather than assumed or omitted.

Enforces only the authorizations that were assigned, so correct assignment is a prerequisite.

Separation of duties constrains which privilege combinations may be assigned to any actor.

Least privilege directly requires that only the minimal necessary privileges are assigned to each actor.

PR.AA-01 supplies credential/identity lifecycle support that can reduce some privilege-assignment errors but does not itself assign, modify, or check privileges, leaving most of CWE-269's risk unaddressed.

Config baselines and default reviews can enforce some privilege-related settings (one facet) but do not address code-level assignment/tracking logic that defines CWE-269.

PR.PS-05 can partially limit exploitability of some privilege issues via execution restrictions, but does not address the core design/implementation flaws of CWE-269 at all.

Access control policy directly prevents incorrect privilege assignment by defining who may receive which rights.

The access-rights control governs the entire lifecycle of privilege assignment, directly eliminating incorrect assignments.

Defining and communicating authorization levels for each role limits the assignment of excessive or unnecessary privileges.

Segregation of duties reduces blast radius of any single incorrect privilege but does not prevent the assignment itself.

Logging every use of privileges and protecting those records makes it harder for an attacker who has obtained elevated rights to operate without leaving evidence.

Restricting privileged utility programs limits exposure from over-privileged accounts but does not address how privileges are assigned.
