It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-56301 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- nuxt (npm): affected from 3.18.0; fixed in 3.21.7\n- nuxt (npm): affected from 3.18.0; fixed in 3.21.7\n- nuxt (npm): affected from 4.0.0; fixed in 4.4.7\n- nuxt (npm): affected from 4.0.0; fixed in 4.4.7\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-2026-56301/ (Markdown: https://insights.sbomify.com/CVE-2026-56301/index.md)","id":"CVE-2026-56301","markdown":"https://insights.sbomify.com/CVE-2026-56301/index.md","name":"CVE-2026-56301","record":{"aliases":["GHSA-534h-c3cw-v3h9"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Nuxt development server","requires_auth":"low_privilege","summary":"Local attackers can read arbitrary files via an unprotected IPC socket in the Nuxt development server on Linux.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"nuxt","vendor":"nuxt"}],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-276","name":"Incorrect Default Permissions"}],"description":"Nuxt 4.0.0 before 4.4.7 and 3.18.0 before 3.21.7, when running the development server (nuxt dev) on Linux, binds the vite-node IPC server to an abstract-namespace Unix socket without permission restrictions, allowing local users to enumerate and connect.
