The component fails to properly validate incoming HTTP `Host` headers, permitting DNS rebinding and Cross-Origin Request Forgery (CSRF) attacks against locally running database proxies.\n\n## TL;DR\nA missing Host header validation in the rmcp HTTP transport allows attackers to execute arbitrary MCP tools on local dynoxide instances via DNS rebinding, leading to unauthenticated local database access.\n\n## Exploit Status: POC\n\n## Technical Details\n\n- **CVSS Score**: 8.8\n- **EPSS Score**: 0.00018\n- **CWE ID**: CWE-346, CWE-350\n- **Attack Vector**: Network (DNS Rebinding)\n- **Exploit Status**: Proof of Concept\n- **Impact**: Data Exfiltration and Manipulation\n\n## Affected Systems\n\n- dynoxide-rs (crates.io)\n- dynoxide (npm)\n- rmcp (Model Context Protocol Rust SDK)\n- **dynoxide**: 0.9.3 - 0.9.12 (Fixed in: `0.9.13`)\n- **rmcp**: < 1.4.0 (Fixed in: `1.4.0`)\n\n## Mitigation\n\n- Upgrade the dynoxide binary to version 0.9.13 or later.\n- Upgrade the rmcp crate dependency to version 1.4.0 or later.\n- Disable the HTTP transport by using the default stdio transport (dynoxide mcp without --http).\n\n**Remediation Steps:**\n1. Identify all local installations of dynoxide.\n2. Update the dynoxide package using cargo install dynoxide-rs --force or npm update dynoxide.\n3. Verify the version by running dynoxide --version.\n4. Ensure start scripts do not include the --http flag if using older versions.\n\n## References\n\n- [NVD CVE Record: CVE-2026-42559](https://nvd.nist.gov/vuln/detail/CVE-2026-42559)\n- [RustSec Advisory: RUSTSEC-2026-0140](https://rustsec.org/advisories/RUSTSEC-2026-0140.html)\n\n\n---\n*Generated by [CVEReports](https://cvereports.com/reports/GHSA-FVH2-GM75-J4J7) - Automated Vulnerability Intelligence*", "creation_timestamp": "2026-05-18T17:40:50.000000Z"} 2026-05-18T17:40:50+00:00 https://vulnerability.circl.lu/sighting/40519821-f193-4327-aaa2-7b0ba1fa471a/export 2026-06-19T23:51:01.188473+00:00 Automation user https://cve.circl.lu/user/automation {"uuid": "40519821-f193-4327-aaa2-7b0ba1fa471a", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2026-42558", "type": "seen", "source": "https://bsky.app/profile/thehackerwire.bsky.social/post/3mny4wzvgc72p", "content": "\ud83d\udfe0 CVE-2026-42558 - High (7.6)\n\nXibo is an open source digital signage platform with a web content management system and Windows ...\n\nhttps://www.thehackerwire.com/vulnerability/CVE-2026-42558/\n\n#infosec #cybersecurity #CVE #vulnerability #security #patchstack", "creation_timestamp": "2026-06-11T02:00:40.157707Z"} 2026-06-11T02:00:40.157707+00:00 https://vulnerability.circl.lu/sighting/16815e14-d9f5-48cb-a405-02c04352d0b2/export 2026-06-19T23:51:01.185027+00:00 Automation user https://cve.circl.lu/user/automation {"uuid": "16815e14-d9f5-48cb-a405-02c04352d0b2", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2026-42558", "type": "seen", "source": "https://bsky.app/profile/postac001.bsky.social/post/3mny7yw76252o", "content": "Xibo CMS\uff084.4.2\u672a\u6e80\uff09\u306eStored XSS\u3068Iframe Sandbox escape\u306e\u8106\u5f31\u6027\u306b\u3088\u308a\u3001DataSet\u6a29\u9650\u3092\u6301\u3064\u30e6\u30fc\u30b6\u30fc\u304cXSS\u3092\u5b9f\u884c\u3067\u304d\u308b\u53ef\u80fd\u6027\u304c\u3042\u308b\u3002\nCVE-2026-42558 CVSS 7.6 | HIGH", "creation_timestamp": "2026-06-11T02:55:23.691274Z"} 2026-06-11T02:55:23.691274+00:00
