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-2024-34273 exists.\n\nAffected packages and fixed versions:\n- njwt (npm): affected all versions; fixed in 2.0.1\n- njwt (npm): affected all versions; fixed in 2.0.1\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-2024-34273/ (Markdown: https://insights.sbomify.com/CVE-2024-34273/index.md)","id":"CVE-2024-34273","markdown":"https://insights.sbomify.com/CVE-2024-34273/index.md","name":"CVE-2024-34273","record":{"aliases":["GHSA-3hvj-2783-34x2"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js JWT library","requires_auth":"none","summary":"Prototype pollution in the njwt library allows attackers to manipulate object prototypes, potentially leading to code execution or privilege escalation.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":5.9,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-1321","name":"Improperly Controlled Modification of Object Prototype Attributes"}],"description":"njwt up to v0.4.0 was discovered to contain a prototype pollution in the Parser.prototype.parse method.","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":"njwt Prototype Pollution vulnerability","id":"CVE-2024-34273","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"other","year":"2024"},"n_packages":2,"n_references":1,"next":{"headline":"Deserialization in n/a","id":"CVE-2024-34274"},"packages":[{"ecosystem":"npm","fixed":["2.0.1"],"introduced":["0"],"last_affected":[],"package":"njwt","purl":null,"source":"GHSA-3hvj-2783-34x2"},{"ecosystem":"npm","fixed":["2.0.1"],"introduced":["0"],"last_affected":[],"package":"njwt","purl":"pkg:npm/njwt","source":"GHSA-3hvj-2783-34x2"}],"prev":{"headline":"Auth bypass in n/a","id":"CVE-2024-34268"},"products":["n/a"],"published":"2024-05-16","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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-02-13","vendors":["n/a"]},"summary":"Prototype pollution in the njwt library allows attackers to manipulate object prototypes, potentially leading to code execution or privilege escalation.","url":"https://insights.sbomify.com/CVE-2024-34273/"}
