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-2020-8268 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- json8-merge-patch (npm): affected all versions; fixed in 1.0.3\n- json8-merge-patch (npm): affected all versions; fixed in 1.0.3\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-2020-8268/ (Markdown: https://insights.sbomify.com/CVE-2020-8268/index.md)","id":"CVE-2020-8268","markdown":"https://insights.sbomify.com/CVE-2020-8268/index.md","name":"CVE-2020-8268","record":{"aliases":["GHSA-8v9x-9xqg-r8mr"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"npm json8-merge-patch","requires_auth":"none","summary":"Attackers can inject or modify global object properties via prototype pollution in the json8-merge-patch library, potentially leading to code execution.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"json8-merge-patch","vendor":"json8-merge-patch_project"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"},{"id":"CWE-471","name":"Modification of Assumed-Immutable Data (MAID)"}],"description":"Prototype pollution vulnerability in json8-merge-patch npm package \u003c 1.0.3 may allow attackers to inject or modify methods and properties of the global object constructor.","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":true,"headline":"Prototype pollution in json8-merge-patch","id":"CVE-2020-8268","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"code_injection","year":"2020"},"n_packages":2,"n_references":1,"next":{"headline":"Privilege escalation in Citrix Virtual Apps and Desktops","id":"CVE-2020-8269"},"packages":[{"ecosystem":"npm","fixed":["1.0.3"],"introduced":["0"],"last_affected":[],"package":"json8-merge-patch","purl":null,"source":"GHSA-8v9x-9xqg-r8mr"},{"ecosystem":"npm","fixed":["1.0.3"],"introduced":["0"],"last_affected":[],"package":"json8-merge-patch","purl":"pkg:npm/json8-merge-patch","source":"GHSA-8v9x-9xqg-r8mr"}],"prev":{"headline":"Auth bypass in UniFi Protect","id":"CVE-2020-8267"},"products":["json8-merge-patch"],"published":"2020-11-09","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":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can inject or modify global object properties via prototype pollution in the json8-merge-patch library, potentially leading to code execution.","url":"https://insights.sbomify.com/CVE-2020-8268/"}
