Summary

CKAN MCP Server before 0.4.112 contains a vulnerability in the ckan_get_mqa_quality and ckan_get_mqa_quality_details tools in src/tools/quality.ts. The isValidMqaServer function validates the server_url parameter with a prefix-only regular expression for dati.gov.it, allowing suffix-host and URL-userinfo values to target an attacker-controlled host and return a spoofed response.

Risk Assessment

An attacker can redirect queries to their own server and return false data, potentially leading to misinformation or data integrity compromise.

Recommendation

Upgrade CKAN MCP Server to version 0.4.112 or later.

Original NVD description (English source)

CKAN MCP Server is a tool for querying CKAN open data portals. Prior to 0.4.112, the ckan_get_mqa_quality and ckan_get_mqa_quality_details tools in src/tools/quality.ts use isValidMqaServer to validate the server_url parameter with a prefix-only regular expression for dati.gov.it, allowing suffix-host and URL-userinfo values to target an attacker-controlled host and return a spoofed response. This issue is fixed in version 0.4.112.
