Common Weakness Enumeration
- CWE-284 - Improper Access ControlThe software does not restrict or incorrectly restricts access to a resource from an unauthorized actor.
- CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')The software uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the software does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
