Weakness Types

What is an AuthZ Vulnerability?

The software performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check. This allows attackers to bypass intended access restrictions.

CVE-2026-115416 has been classified to as an AuthZ vulnerability or weakness.

What is a Separation of Privilege Vulnerability?

The product does not sufficiently compartmentalize functionality or processes that require different privilege levels, rights, or permissions. When a weakness occurs in functionality that is accessible by lower-privileged users, then without strong boundaries, an attack might extend the scope of the damage to higher-privileged users.

CVE-2026-115416 has been classified to as a Separation of Privilege vulnerability or weakness.
