An archive entry's FullName is used to build an extraction path without checking that the result stays inside the target directory (zip slip). A crafted archive can overwrite arbitrary files.
Category: SECURITY · Engine rule severity: WARNING
How to fix it
Resolve Path.GetFullPath(Path.Combine(dest, entry.FullName)) and skip the entry unless it starts with the full destination path plus a separator, or use ZipFile.ExtractToDirectory, which performs this check.
