It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-3959 exists.\n\nAffected product: 0xKoda WireMCP. 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-2026-3959/ (Markdown: https://insights.sbomify.com/CVE-2026-3959/index.md)","id":"CVE-2026-3959","markdown":"https://insights.sbomify.com/CVE-2026-3959/index.md","name":"CVE-2026-3959","record":{"aliases":["GHSA-v6jp-f2qq-3m24"],"analysis":{"component_type":"library","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"MCP server library","requires_auth":"low_privilege","summary":"Local attackers can execute arbitrary OS commands via the Tshark CLI handler in the WireMCP library, requiring immediate attention from users of this MCP server.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"},{"id":"CWE-77","name":"Improper Neutralization of Special Elements used in a Command"}],"description":"A vulnerability was found in 0xKoda WireMCP up to 7f45f8b2b4adeb76be8c6227eefb38533fdd6b1e.
