Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-3484 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- mcp-nmap-server (npm): affected all versions up to 1.0.1; no fix listed\n- mcp-nmap-server (npm): affected all versions up to 1.0.1; no fix listed\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-2026-3484/ (Markdown: https://insights.sbomify.com/CVE-2026-3484/index.md)","id":"CVE-2026-3484","markdown":"https://insights.sbomify.com/CVE-2026-3484/index.md","name":"CVE-2026-3484","record":{"aliases":["GHSA-xc68-rrqc-qgq3"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Nmap MCP server","requires_auth":"low_privilege","summary":"Remote attackers can execute arbitrary commands via the Nmap CLI handler in the nmap-mcp-server library, requiring a patch to mitigate.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[{"product":"mcp_nmap_server","vendor":"phialsbasement"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:X","version":"4.0"},"cwes":[{"id":"CWE-77","name":"Improper Neutralization of Special Elements used in a Command"},{"id":"CWE-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"}],"description":"A vulnerability was detected in PhialsBasement nmap-mcp-server up to bee6d23547d57ae02460022f7c78ac0893092e38.
