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-2020-17159 and fix it if it is affected.\n\nWhat it is: CVE-2020-17159 is a high-severity code injection vulnerability in Microsoft Visual Studio Code Language Support for Java Extension, published on 9 Dec 2020. 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-2020-17159 in the wild and no public exploit code.\n\nAffected product: Microsoft Visual Studio Code Language Support for Java 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-2020-17159/ (Markdown: https://insights.sbomify.com/CVE-2020-17159/index.md)","id":"CVE-2020-17159","markdown":"https://insights.sbomify.com/CVE-2020-17159/index.md","name":"CVE-2020-17159","record":{"aliases":["GHSA-p9fx-5rv4-h3wp"],"analysis":{"component_type":"developer_tool","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"VS Code Java Extension","requires_auth":"none","summary":"Attackers can execute arbitrary code via the Visual Studio Code Java Extension Pack, requiring users to update the extension.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"language_support_for_java","vendor":"redhat"}],"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 Java Extension Pack 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 Java Extension Pack Remote Code Execution Vulnerability","id":"CVE-2020-17159","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2020-17160"},"packages":[],"prev":{"headline":"Microsoft Dynamics 365 for Finance and Operations (on-premises) Remote Code Execution Vulnerability","id":"CVE-2020-17158"},"products":["Visual Studio Code Language Support for Java Extension"],"published":"2020-12-09","related":[],"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-06-09","vendors":["Microsoft"]},"summary":"Attackers can execute arbitrary code via the Visual Studio Code Java Extension Pack, requiring users to update the extension.","url":"https://insights.sbomify.com/CVE-2020-17159/"}
