Summary
CKAN MCP Server is a tool for querying CKAN open data portals. Prior to 0.4.112, error paths reflect raw upstream response bodies and internal exception messages back to the caller instead of a sanitized, generic message. When the server is pointed at (or redirected/SSRF'd to) a host that returns a non-CKAN response, or when an internal exception occurs, the caller receives verbatim upstream content and internal detail (hostnames, internal IPs, DB errors, stack fragments). This vulnerability is fixed in 0.4.112.
Risk Assessment
The risk includes exposure of sensitive infrastructure information, potentially facilitating further attacks and compromising system security.
Recommendation
Update CKAN MCP Server to version 0.4.112 or later and configure the server to avoid directing requests to untrusted hosts.
