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-2026-58043 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-2026-58043/ (Markdown: https://insights.sbomify.com/CVE-2026-58043/index.md)","id":"CVE-2026-58043","markdown":"https://insights.sbomify.com/CVE-2026-58043/index.md","name":"CVE-2026-58043","record":{"aliases":["ALPINE-CVE-2026-58043","AZL-94346","BELL-CVE-2026-58043","BIT-node-2026-58043","BIT-node-min-2026-58043","CLEANSTART-2026-RX91523","DEBIAN-CVE-2026-58043","ECHO-7674-da0a-19ed","GHSA-qrq2-c54w-wgqm","MINI-2c2r-7mjq-p9mm","MINI-2jcc-7mwp-m84g","MINI-2pfw-v7wp-wxwg","MINI-3pq9-ghjg-q2rw","MINI-925g-jxh8-fjr6","MINI-95w6-c7jm-257w","MINI-qx9g-hg7v-fm8q","MINI-wq8h-x5fw-wqw5","UBUNTU-CVE-2026-58043"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Node.js runtime","requires_auth":"low_privilege","summary":"Attackers can bypass Node.js permission model restrictions to read or write files outside the allowed paths when the permission flag is enabled.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"node.js","vendor":"nodejs"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:N","version":"3.0"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"A flaw in Node.js Permission Model enforcement can over-grant filesystem access across radix-tree prefix boundaries.\r\n\r\nUnder `--permission`, an attacker who is granted access to one path can abuse boundary handling to read from or write to paths outside the intended filesystem allowlist.\r\n\r\nThis vulnerability affects Node.js **main**, **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":"2026-10-23T23:44:09Z","kind":"github_poc","ref":"https://github.com/CompleteTech-Security/node-cve-2026-58043-check","stars":0,"title":"Offline Node.js evidence checker for CVE-2026-58043: Permission Model path-prefix over-grant.
