| shiva | pip | <= 0.10.0 |
The vulnerability arises from the unsafe use of Flask's send_file function in shiva-server/shiva/fileserver.py (line 81). The application constructs the absolute_path using os.path.join with a user-controlled relative_path parameter. Since os.path.join ignores previous path components when encountering an absolute path, attackers can supply paths like '/../../etc/passwd' to traverse directories. The direct use of send_file with this untrusted absolute_path enables path traversal, as confirmed by the GitHub advisory and CVE description.
