SCA: security update for @aborruso/ckan-mcp-server (GHSA-vqff-r82h-9crc)

low Tenable Cloud Security Plugin ID 476083

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - CKAN MCP Server is a tool for querying CKAN open data portals. Prior to 0.4.112, the DataStore table UI in
 src/resources/datastore-table-ui.ts accepts window message events without validating event.origin and
 sends JSON-RPC messages through postMessage with a wildcard target origin. A frame that can reach the
 embedded document can inject fabricated fields or records, spoof pending ui/initialize responses, disrupt
 the MCP UI handshake, or receive outbound messages when the resource is embedded by an untrusted parent.
 Values are HTML escaped, so the demonstrated content injection is display spoofing rather than script
 execution, and exploitability depends on the host embedding model. This issue is fixed in version 0.4.112.
 (CVE-2026-76894)

Solution

Update the @aborruso/ckan-mcp-server library and its related packages to version 0.4.112 or later.
