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-2026-58039 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- node (Bitnami): affected all versions; fixed in 22.23.2, 24.18.1, 26.5.1\n- node-min (Bitnami): affected all versions; fixed in 22.23.2, 24.18.1, 26.5.1\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-2026-58039/ (Markdown: https://insights.sbomify.com/CVE-2026-58039/index.md)","id":"CVE-2026-58039","markdown":"https://insights.sbomify.com/CVE-2026-58039/index.md","name":"CVE-2026-58039","record":{"aliases":["ALPINE-CVE-2026-58039","AZL-94343","BELL-CVE-2026-58039","BIT-node-2026-58039","BIT-node-min-2026-58039","CLEANSTART-2026-SR40385","DEBIAN-CVE-2026-58039","ECHO-069b-5add-3223","GHSA-4qw5-6jhx-9hfx","MINI-7p39-6m5m-87mv","MINI-chx4-7mf7-pmgm","MINI-f4vg-fxqm-qwgr","MINI-jxpx-v692-36mq","MINI-p76j-7cp5-pmvf","MINI-qj28-843c-5v62","MINI-vmxf-6x2v-9j4h","MINI-xh8w-mgxm-4mjg","UBUNTU-CVE-2026-58039"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Node.js runtime","requires_auth":"low_privilege","summary":"Node.js Permission Model flaw allows process.report to write files outside allowed paths, bypassing security boundaries in specific configurations.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[],"cvss":{"score":3.3,"severity":"low","source":"cna","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"A flaw in Node.js Permission Model enforcement allows process.report writes (and overwrites) files outside --allow-fs-write paths.\n\nThis can lead to confidentiality impact or bypass of the intended security boundary under affected configurations.\n\nThis vulnerability affects Node.js **22.x**, **24.x**, and **26.x**.","ecosystems":["Bitnami"],"exploits":{"exploitdb":0,"first_seen":"2026-10-23","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-10-23T23:45:55Z","kind":"github_poc","ref":"https://github.com/CompleteTech-Security/node-cve-2026-58039-check","stars":0,"title":"Offline Node.js evidence checker for CVE-2026-58039: Permission Model process-report filesystem bypass.
