It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2021-27081 and fix it if it is affected.\n\nWhat it is: CVE-2021-27081 is a high-severity code injection vulnerability in Microsoft Visual Studio Code ESLint extension, published on 11 Mar 2021. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-27081 in the wild and no public exploit code.\n\nAffected product: Microsoft Visual Studio Code ESLint extension. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2021-27081/ (Markdown: https://insights.sbomify.com/CVE-2021-27081/index.md)","id":"CVE-2021-27081","markdown":"https://insights.sbomify.com/CVE-2021-27081/index.md","name":"CVE-2021-27081","record":{"aliases":["GHSA-296j-2h87-8rxh"],"analysis":{"component_type":"developer_tool","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"VS Code ESLint extension","requires_auth":"none","summary":"Attackers can execute arbitrary code via the Visual Studio Code ESLint extension, requiring users to update the extension.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"eslint","vendor":"microsoft"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[],"description":"Visual Studio Code ESLint Extension Remote Code Execution Vulnerability","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Visual Studio Code ESLint Extension Remote Code Execution Vulnerability","id":"CVE-2021-27081","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Quantum Development Kit for Visual Studio Code Remote Code Execution Vulnerability","id":"CVE-2021-27082"},"packages":[],"prev":{"headline":"Azure Sphere Unsigned Code Execution Vulnerability","id":"CVE-2021-27080"},"products":["Microsoft Visual Studio Code ESLint extension"],"published":"2021-03-11","related":[{"cvss_score":8.8,"headline":"Code injection in Microsoft Visual Studio Code ESLint extension","id":"CVE-2020-1481","kev_date_added":null,"published":"2020-07-14"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-08-19","vendors":["Microsoft"]},"summary":"Attackers can execute arbitrary code via the Visual Studio Code ESLint extension, requiring users to update the extension.","url":"https://insights.sbomify.com/CVE-2021-27081/"}
