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-2026-21711 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- node (Bitnami): affected from 25.0.0; fixed in 25.8.2\n- node-min (Bitnami): affected from 25.0.0; fixed in 25.8.2\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-2026-21711/ (Markdown: https://insights.sbomify.com/CVE-2026-21711/index.md)","id":"CVE-2026-21711","markdown":"https://insights.sbomify.com/CVE-2026-21711/index.md","name":"CVE-2026-21711","record":{"aliases":["BIT-node-2026-21711","BIT-node-min-2026-21711","GHSA-vcqx-cqfc-xc2r","MINI-8rfx-g9j3-xg28","UBUNTU-CVE-2026-21711"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Node.js runtime","requires_auth":"low_privilege","summary":"Attackers can bypass network restrictions in Node.js Permission Model to create local IPC endpoints when network access is disabled.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"node.js","vendor":"nodejs"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L","version":"3.0"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"A flaw in Node.js Permission Model network enforcement leaves Unix Domain Socket (UDS) server operations without the required permission checks, while all comparable network paths correctly enforce them.\r\n\r\nAs a result, code running under `--permission` without `--allow-net` can create and expose local IPC endpoints, allowing communication with other processes on the same host outside of the intended network restriction boundary.\r\n\r\nThis vulnerability affects Node.js **25.x** processes using the Permission Model where `--allow-net` is intentionally omitted to restrict network access.
