CWE-216 (容器错误) — Vulnerability Class 4

CWE-216 is a deprecated entry that originally categorized containment errors, also known as container errors, within software systems. Although the weakness is no longer actively tracked due to its vague structure and ambiguous terminology, it historically referred to failures in isolating components or data within logical boundaries. Exploitation typically involved bypassing these containment mechanisms to access restricted resources or execute unauthorized operations, often leading to privilege escalation or data leakage. Developers avoided such issues by implementing strict access controls, validating input boundaries, and ensuring clear separation between trusted and untrusted execution environments. The deprecation highlights the need for precise definitions in security frameworks, as the term "container" carries varied meanings that can obscure specific vulnerability patterns.
