Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-20086 exists.\n\nAffected packages and fixed versions:\n- jquery-bbq (npm): affected all versions up to 1.2.1; no fix listed\n- jquery-bbq (npm): affected all versions up to 1.2.1; 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-2021-20086/ (Markdown: https://insights.sbomify.com/CVE-2021-20086/index.md)","id":"CVE-2021-20086","markdown":"https://insights.sbomify.com/CVE-2021-20086/index.md","name":"CVE-2021-20086","record":{"aliases":["GHSA-7w8j-85wm-6xfq"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript library","requires_auth":"low_privilege","summary":"Prototype pollution in jquery-bbq allows attackers to inject properties into Object.prototype, potentially leading to code execution or security bypasses.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"tenable","cpe":[{"product":"jquery-bbq","vendor":"jquery-bbq_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 jquery-bbq 1.2.1 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":1,"refs":[{"date":null,"kind":"nuclei","ref":"http/cves/2021/CVE-2021-20086.yaml","stars":null,"title":"Odoo Apps - Cross-Site Scripting via Prototype Pollution"}],"tier":"weaponised"},"has_fix":false,"headline":"Prototype Pollution in jquery-bbq","id":"CVE-2021-20086","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-deparam","id":"CVE-2021-20087"},"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["1.2.1"],"package":"jquery-bbq","purl":null,"source":"GHSA-7w8j-85wm-6xfq"},{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["1.2.1"],"package":"jquery-bbq","purl":"pkg:npm/jquery-bbq","source":"GHSA-7w8j-85wm-6xfq"}],"prev":{"headline":"Prototype Pollution in backbone-query-parameters","id":"CVE-2021-20085"},"products":["jquery-bbq"],"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)"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2025-11-03","vendors":["n/a"]},"summary":"Prototype pollution in jquery-bbq allows attackers to inject properties into Object.prototype, potentially leading to code execution or security bypasses.","url":"https://insights.sbomify.com/CVE-2021-20086/"}
