Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-20085 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- backbone-query-parameters (npm): affected all versions up to 0.4.0; no fix listed\n- backbone-query-parameters (npm): affected all versions up to 0.4.0; 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-2021-20085/ (Markdown: https://insights.sbomify.com/CVE-2021-20085/index.md)","id":"CVE-2021-20085","markdown":"https://insights.sbomify.com/CVE-2021-20085/index.md","name":"CVE-2021-20085","record":{"aliases":["GHSA-8qpm-5c82-rf96"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript library","requires_auth":"low_privilege","summary":"Prototype pollution in backbone-query-parameters allows attackers to inject properties into Object.prototype, potentially leading to code execution or privilege escalation.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"tenable","cpe":[{"product":"backbone-query-parameters","vendor":"backbone-query-parameters_project"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/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":"Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution') in backbone-query-parameters 0.4.0 allows a malicious user to inject properties into Object.prototype.","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 backbone-query-parameters","id":"CVE-2021-20085","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"code_injection","year":"2021"},"n_packages":2,"n_references":1,"next":{"headline":"Prototype Pollution in jquery-bbq","id":"CVE-2021-20086"},"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["0.4.0"],"package":"backbone-query-parameters","purl":null,"source":"GHSA-8qpm-5c82-rf96"},{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["0.4.0"],"package":"backbone-query-parameters","purl":"pkg:npm/backbone-query-parameters","source":"GHSA-8qpm-5c82-rf96"}],"prev":{"headline":"Code injection in jQuery Sparkle","id":"CVE-2021-20084"},"products":["backbone-query-parameters"],"published":"2021-04-23","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 backbone-query-parameters allows attackers to inject properties into Object.prototype, potentially leading to code execution or privilege escalation.","url":"https://insights.sbomify.com/CVE-2021-20085/"}
