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-2026-21715 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- node (Bitnami): affected all versions; fixed in 20.20.2, 22.22.2, 24.14.1, 25.8.2\n- node-min (Bitnami): affected all versions; fixed in 20.20.2, 22.22.2, 24.14.1, 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-2026-21715/ (Markdown: https://insights.sbomify.com/CVE-2026-21715/index.md)","id":"CVE-2026-21715","markdown":"https://insights.sbomify.com/CVE-2026-21715/index.md","name":"CVE-2026-21715","record":{"aliases":["ALPINE-CVE-2026-21715","AZL-81230","AZL-81263","BELL-CVE-2026-21715","BIT-node-2026-21715","BIT-node-min-2026-21715","CLEANSTART-2026-KY64095","DEBIAN-CVE-2026-21715","GHSA-8jgr-5cgv-g667","MINI-346r-233v-8xx8","MINI-883f-42qv-6h9q","MINI-cvx5-gqpr-47w9","MINI-j7j2-qhh9-ffhm","MINI-mf96-89h3-6cc3","MINI-v6q8-j2gw-v3xf","MINI-w7pf-f3gv-22pr","UBUNTU-CVE-2026-21715"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Node.js runtime","requires_auth":"low_privilege","summary":"Attackers can bypass Node.js filesystem read restrictions using fs.realpathSync.native() to enumerate files outside permitted directories.","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":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-732","name":"Incorrect Permission Assignment for Critical Resource"}],"description":"A flaw in Node.js Permission Model filesystem enforcement leaves `fs.realpathSync.native()` without the required read permission checks, while all comparable filesystem functions correctly enforce them.\r\n\r\nAs a result, code running under `--permission` with restricted `--allow-fs-read` can still use `fs.realpathSync.native()` to check file existence, resolve symlink targets, and enumerate filesystem paths outside of permitted directories.\r\n\r\nThis vulnerability affects **20.x, 22.x, 24.x, and 25.x** processes using the Permission Model where `--allow-fs-read` is intentionally restricted.","ecosystems":["Bitnami"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Missing authorization in node","id":"CVE-2026-21715","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"nodejs:node.js","products":["nodejs:node.js"],"type":"missing_authorization","year":"2026"},"n_packages":2,"n_references":1,"next":{"headline":"Security feature bypass in node","id":"CVE-2026-21716"},"packages":[{"ecosystem":"Bitnami","fixed":["20.20.2","22.22.2","24.14.1","25.8.2"],"introduced":["0","21.0.0","23.0.0","25.0.0"],"last_affected":[],"package":"node","purl":"pkg:bitnami/node","source":"BIT-node-2026-21715"},{"ecosystem":"Bitnami","fixed":["20.20.2","22.22.2","24.14.1","25.8.2"],"introduced":["0","21.0.0","23.0.0","25.0.0"],"last_affected":[],"package":"node-min","purl":"pkg:bitnami/node-min","source":"BIT-node-min-2026-21715"}],"prev":{"headline":"Denial of service in node","id":"CVE-2026-21714"},"products":["node"],"published":"2026-03-30","related":[{"cvss_score":9.8,"headline":"Security feature bypass in Node","id":"CVE-2023-32002","kev_date_added":null,"published":"2023-08-21"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2016-6303","kev_date_added":null,"published":"2016-09-16"},{"cvss_score":9.1,"headline":"Security feature bypass in Node.js","id":"CVE-2017-15896","kev_date_added":null,"published":"2017-12-11"},{"cvss_score":8.8,"headline":"Server-side request forgery in Node.js","id":"CVE-2018-7160","kev_date_added":null,"published":"2018-05-17"},{"cvss_score":8.1,"headline":"Misconfiguration in Node.js","id":"CVE-2018-12120","kev_date_added":null,"published":"2018-11-28"},{"cvss_score":7.9,"headline":"Path traversal in Node","id":"CVE-2024-21891","kev_date_added":null,"published":"2024-02-20"},{"cvss_score":7.9,"headline":"Path traversal in Node","id":"CVE-2024-21896","kev_date_added":null,"published":"2024-02-20"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-17","vendors":["nodejs"]},"summary":"Attackers can bypass Node.js filesystem read restrictions using fs.realpathSync.native() to enumerate files outside permitted directories.","url":"https://insights.sbomify.com/CVE-2026-21715/"}
