An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-26111 exists.\n\nAffected packages and fixed versions:\n- @nubosoftware/node-static (npm): affected all versions up to 0.7.11; no fix listed\n- @nubosoftware/node-static (npm): affected all versions up to 0.7.11; no fix listed\n- node-static (npm): affected all versions up to 0.7.11; no fix listed\n- node-static (npm): affected all versions up to 0.7.11; no fix listed\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-2023-26111/ (Markdown: https://insights.sbomify.com/CVE-2023-26111/index.md)","id":"CVE-2023-26111","markdown":"https://insights.sbomify.com/CVE-2023-26111/index.md","name":"CVE-2023-26111","record":{"aliases":["GHSA-5g97-whc9-8g7j"],"analysis":{"component_type":"library","fix_type":"no_fix_stated","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js static file server","requires_auth":"none","summary":"Attackers can read arbitrary files from the server due to improper path sanitization in the node-static library.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"snyk","cpe":[{"product":"\\@nubosoftware\\/node-static","vendor":"\\@nubosoftware\\/node-static_project"},{"product":"node-static","vendor":"node-static_project"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N/E:P","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"All versions of the package @nubosoftware/node-static; all versions of the package node-static are vulnerable to Directory Traversal due to improper file path sanitization in the startsWith() method in the servePath function.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"node-static and @nubosoftware/node-static vulnerable to Directory Traversal","id":"CVE-2023-26111","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"path_traversal","year":"2023"},"n_packages":4,"n_references":4,"next":{"headline":"configobj ReDoS exploitable by developer using values in a server-side configuration file","id":"CVE-2023-26112"},"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["0.7.11"],"package":"@nubosoftware/node-static","purl":null,"source":"GHSA-5g97-whc9-8g7j"},{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["0.7.11"],"package":"@nubosoftware/node-static","purl":"pkg:npm/%40nubosoftware/node-static","source":"GHSA-5g97-whc9-8g7j"},{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["0.7.11"],"package":"node-static","purl":null,"source":"GHSA-5g97-whc9-8g7j"},{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["0.7.11"],"package":"node-static","purl":"pkg:npm/node-static","source":"GHSA-5g97-whc9-8g7j"}],"prev":{"headline":"node-bluetooth is vulnerable to Buffer Overflow via the findSerialPortChannel method due to improper user input length validation","id":"CVE-2023-26110"},"products":["@nubosoftware/node-static","node-static"],"published":"2023-03-06","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-03-05","vendors":["n/a"]},"summary":"Attackers can read arbitrary files from the server due to improper path sanitization in the node-static library.","url":"https://insights.sbomify.com/CVE-2023-26111/"}
