CVE-2023-32321Network attack vector

Remote code execution via crafted resource identifiers

Published May 26, 2023 · Updated Jan 14, 2025

Path traversal in CKAN before 2.9.9 and CKAN 2.10.0 allows remote authenticated users to write files via crafted resource IDs. ResourceUploader uses an attacker-supplied resource ID when handling resource_create or package_update uploads, allowing arbitrary-path writes, resource disclosure, and overwrites. Dataset create or edit permission is required, and code execution additionally requires the file-backed Beaker session store, whose unsafe pickle loading processes the written session data.
