Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-18905 in the wild and no public exploit code.\n\nAffected product: IBM ContextForge MCP Gateway (`mcp-contextforge-gateway`). No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-18905/ (Markdown: https://insights.sbomify.com/CVE-2026-18905/index.md)","id":"CVE-2026-18905","markdown":"https://insights.sbomify.com/CVE-2026-18905/index.md","name":"CVE-2026-18905","record":{"aliases":["GHSA-p4cr-j9h3-9c8p"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"MCP Gateway","requires_auth":"low_privilege","summary":"Remote authenticated attackers can exploit DNS rebinding to perform server-side request forgery and obtain sensitive information.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"contextforge","vendor":"ibm"}],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"}],"description":"IBM ContextForge MCP Gateway (`mcp-contextforge-gateway`) \u003c= v1.0.6 MCP Context Forge could allow a remote authenticated attacker to obtain sensitive information due to a DNS rebinding vulnerability during tool invocation.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"IBM ContextForge MCP Gateway is affected by server-side request forgery via DNS TOCTOU at tool invocation","id":"CVE-2026-18905","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"ssrf","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"PathTravelsal Vulnerability in com.talpa.hibrowser","id":"CVE-2026-18907"},"packages":[],"prev":{"headline":"Auth bypass in Langflow OSS","id":"CVE-2026-18904"},"products":["ContextForge MCP Gateway (`mcp-contextforge-gateway`)"],"published":"2026-09-04","related":[{"cvss_score":9.8,"headline":"IBM ContextForge MCP Gateway is affected by use of default credentials","id":"CVE-2026-78573","kev_date_added":null,"published":"2026-09-10"},{"cvss_score":8.8,"headline":"IBM ContextForge MCP Gateway is affected by credential disclosure and privilege escalation via jq filter execution","id":"CVE-2026-18486","kev_date_added":null,"published":"2026-09-04"},{"cvss_score":8.2,"headline":"Server-side request forgery in ContextForge MCP Gateway","id":"CVE-2026-77822","kev_date_added":null,"published":"2026-09-04"},{"cvss_score":7.4,"headline":"IBM ContextForge Translate is affected by cross-client credential context confusion","id":"CVE-2026-18489","kev_date_added":null,"published":"2026-09-04"},{"cvss_score":4.9,"headline":"IBM ContextForge MCP Gateway is affected by path traversal","id":"CVE-2026-77825","kev_date_added":null,"published":"2026-09-24"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-04","vendors":["IBM"]},"summary":"Remote authenticated attackers can exploit DNS rebinding to perform server-side request forgery and obtain sensitive information.","url":"https://insights.sbomify.com/CVE-2026-18905/"}
