CVE-2026-73844

3.7 lowEPSS 0.4%

Low (3.7). EPSS 0.4% chance of exploitation in the next 30 days. Fixed in @aborruso/ckan-mcp-server 0.4.112.

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.
