The application's server URL validation mechanism checked hostnames only as literal strings without performing pre-connection DNS resolution. An attacker can bypass these checks using hostnames that resolve to loopback, private, or link-local IP addresses, including the AWS Instance Metadata Service (IMDS). This is the third documented bypass of this protection mechanism, succeeding previous incomplete mitigations in CVE-2026-33060 and CVE-2026-53509.\n\n## TL;DR\nA Server-Side Request Forgery (SSRF) vulnerability in @aborruso/ckan-mcp-server before v0.4.108 allows low-privilege remote attackers to query local or internal network endpoints, including AWS IMDS, by passing domains that resolve to restricted IPs, bypassing the string-only validation checks.\n\n## Exploit Status: POC\n\n## Technical Details\n\n- **CWE ID**: CWE-918\n- **Attack Vector**: Network (AV:N)\n- **CVSS Severity Score**: 5.7 (Medium)\n- **EPSS Score**: 0.00221 (Percentile: 12.95%)\n- **Exploit Status**: poc\n- **KEV Status**: Not Listed\n\n## Affected Systems\n\n- Node.js applications running @aborruso/ckan-mcp-server version &amp;lt; 0.4.108\n\n## Mitigation\n\n- Upgrade @aborruso/ckan-mcp-server to version 0.4.108 or higher to enforce DNS-resolved IP checks.\n- Implement outbound network firewall constraints (egress filtering) to block requests to loopback addresses, private networks, and cloud metadata targets.\n- Enable the domain validation allowlist feature using the CKAN_ALLOWED_DOMAINS environment variable to restrict outbound connections to approved targets.\n\n**Remediation Steps:**\n1. Run 'npm install @aborruso/ckan-mcp-server@latest' to update the package to v0.4.108 or higher.\n2. Configure environment configuration using 'export CKAN_ALLOWED_DOMAINS=\"data.gov,open.canada.ca,dati.gov.it\"' to limit target access.\n3. Configure cloud security group or local iptables firewall policies to deny traffic from the MCP server container to 169.254.169.254 and 127.0.0.1.\n\n## References\n\n- [GitHub Security Advisory GHSA-798p-78g2-v556](https://github.com/ondata/ckan-mcp-server/security/advisories/GHSA-798p-78g2-v556)\n- [Fix Commit in Repository](https://github.com/ondata/ckan-mcp-server/commit/bb7439b553b9f965adc3d43bcd415c42eebe2f40)\n- [Release Tag v0.4.108](https://github.com/ondata/ckan-mcp-server/releases/tag/v0.4.108)\n- [GitHub Advisory Database Reference (CVE-2026-33060)](https://github.com/advisories/GHSA-3xm7-qw7j-qc8v)\n- [GitHub Advisory Database Reference (CVE-2026-53509)](https://github.com/advisories/GHSA-g84h-j7jj-x32p)\n\n\n---\n*Generated by [CVEReports](https://cvereports.com/reports/CVE-2026-61612) - Automated Vulnerability Intelligence*", "creation_timestamp": "2026-09-22T15:32:08.331956Z"}</description>
