An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-25946 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- nconf-toml (npm): affected from 0.0.1 up to 0.0.2; no fix listed\n- nconf-toml (npm): affected from 0.0.1 up to 0.0.2; 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-2021-25946/ (Markdown: https://insights.sbomify.com/CVE-2021-25946/index.md)","id":"CVE-2021-25946","markdown":"https://insights.sbomify.com/CVE-2021-25946/index.md","name":"CVE-2021-25946","record":{"aliases":["GHSA-hx7j-43w2-7rj7"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"npm toml parser","requires_auth":"none","summary":"Prototype pollution in nconf-toml allows attackers to cause denial of service and potentially execute remote code.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Mend","cpe":[{"product":"nconf-toml","vendor":"nconf-toml_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":"Prototype pollution vulnerability in `nconf-toml` versions 0.0.1 through 0.0.2 allows an attacker to cause a denial of service and may lead to remote code execution.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Prototype pollution in nconf-toml","id":"CVE-2021-25946","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"other","year":"2021"},"n_packages":2,"n_references":2,"next":{"headline":"Prototype pollution in nestie","id":"CVE-2021-25947"},"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0.0.1"],"last_affected":["0.0.2"],"package":"nconf-toml","purl":null,"source":"GHSA-hx7j-43w2-7rj7"},{"ecosystem":"npm","fixed":[],"introduced":["0.0.1"],"last_affected":["0.0.2"],"package":"nconf-toml","purl":"pkg:npm/nconf-toml","source":"GHSA-hx7j-43w2-7rj7"}],"prev":{"headline":"Prototype pollution vulnerability in js-extend","id":"CVE-2021-25945"},"products":["nconf-toml"],"published":"2021-05-25","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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["n/a"]},"summary":"Prototype pollution in nconf-toml allows attackers to cause denial of service and potentially execute remote code.","url":"https://insights.sbomify.com/CVE-2021-25946/"}
