      ▼Vulnerability Mapping Notes
      Usage:Allowed
      Reason:Acceptable-Use
      Rationale:

      This CWE entry is at the Variant level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.

      Comments:

      Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.
