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-2023-38894 exists.\n\nAffected packages and fixed versions:\n- tree-kit (npm): affected all versions; fixed in 0.7.5\n- tree-kit (npm): affected all versions; fixed in 0.7.5\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-2023-38894/ (Markdown: https://insights.sbomify.com/CVE-2023-38894/index.md)","id":"CVE-2023-38894","markdown":"https://insights.sbomify.com/CVE-2023-38894/index.md","name":"CVE-2023-38894","record":{"aliases":["GHSA-5p42-m6f3-hpmj"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript utility library","requires_auth":"none","summary":"A remote attacker can execute arbitrary code via prototype pollution in the extend function of the Tree-kit library.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"tree_kit","vendor":"tree_kit_project"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-1321","name":"Improperly Controlled Modification of Object Prototype Attributes"}],"description":"A Prototype Pollution issue in Cronvel Tree-kit v.0.7.4 and before allows a remote attacker to execute arbitrary code via the extend 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":true,"headline":"tree-kit Prototype Pollution vulnerability","id":"CVE-2023-38894","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"code_injection","year":"2023"},"n_packages":2,"n_references":2,"next":{"headline":"LangChain vulnerable to arbitrary code execution","id":"CVE-2023-38896"},"packages":[{"ecosystem":"npm","fixed":["0.7.5"],"introduced":["0"],"last_affected":[],"package":"tree-kit","purl":null,"source":"GHSA-5p42-m6f3-hpmj"},{"ecosystem":"npm","fixed":["0.7.5"],"introduced":["0"],"last_affected":[],"package":"tree-kit","purl":"pkg:npm/tree-kit","source":"GHSA-5p42-m6f3-hpmj"}],"prev":{"headline":"SQL injection in n/a","id":"CVE-2023-38891"},"products":["n/a"],"published":"2023-08-16","related":[{"cvss_score":5.5,"headline":"cronvel tree-kit prototype pollution","id":"CVE-2021-4278","kev_date_added":null,"published":"2022-12-25"}],"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":"total"},"state":"PUBLISHED","updated":"2026-07-09","vendors":["n/a"]},"summary":"A remote attacker can execute arbitrary code via prototype pollution in the extend function of the Tree-kit library.","url":"https://insights.sbomify.com/CVE-2023-38894/"}
