CVE-2026-73845 · CKAN MCP Server: MQA server allowlist bypass via unanchored regex (`isValidMqaServer`)
This page contains facts from public vulnerability sources. Check the original advisory before updating.
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.
