An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-28161 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- @theia/console (npm): affected all versions; fixed in 1.8.1\n- @theia/console (npm): affected all versions; fixed in 1.8.1\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-2021-28161/ (Markdown: https://insights.sbomify.com/CVE-2021-28161/index.md)","id":"CVE-2021-28161","markdown":"https://insights.sbomify.com/CVE-2021-28161/index.md","name":"CVE-2021-28161","record":{"aliases":["GHSA-cwg9-c9cr-p5fq"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Eclipse Theia IDE","requires_auth":"none","summary":"Attackers can inject arbitrary JavaScript into the Eclipse Theia debug console due to missing HTML escaping, potentially executing code in the user's context.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"eclipse","cpe":[{"product":"theia","vendor":"eclipse"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"In Eclipse Theia versions up to and including 1.8.0, in the debug console there is no HTML escaping, so arbitrary Javascript code can be injected.","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":"Improper Neutralization of Input in Theia console","id":"CVE-2021-28161","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"xss","year":"2021"},"n_packages":2,"n_references":1,"next":{"headline":"Command Injection in @theia/messages","id":"CVE-2021-28162"},"packages":[{"ecosystem":"npm","fixed":["1.8.1"],"introduced":["0"],"last_affected":[],"package":"@theia/console","purl":null,"source":"GHSA-cwg9-c9cr-p5fq"},{"ecosystem":"npm","fixed":["1.8.1"],"introduced":["0"],"last_affected":[],"package":"@theia/console","purl":"pkg:npm/%40theia/console","source":"GHSA-cwg9-c9cr-p5fq"}],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2021-28160"},"products":["Eclipse Theia"],"published":"2021-03-12","related":[{"cvss_score":9.8,"headline":"XML external entity in Eclipse Theia","id":"CVE-2021-34436","kev_date_added":null,"published":"2021-09-02"},{"cvss_score":9.6,"headline":"Cross-site Scripting (XSS) in Eclipse Theia","id":"CVE-2020-27224","kev_date_added":null,"published":"2021-02-24"},{"cvss_score":8.8,"headline":"File upload in Eclipse Theia","id":"CVE-2026-60009","kev_date_added":null,"published":"2026-08-05"},{"cvss_score":8.8,"headline":"Remote code execution in Eclipse Theia","id":"CVE-2021-34435","kev_date_added":null,"published":"2021-09-01"},{"cvss_score":8.4,"headline":"[Eclipse Theia] Indirect Prompt Injection via Adversarial Workspace File and Directory Names in AI Chat","id":"CVE-2026-44688","kev_date_added":null,"published":"2026-06-18"},{"cvss_score":8.4,"headline":"[Eclipse Theia] Arbitrary Command Execution via Untrusted Workspace Task Definitions","id":"CVE-2026-44691","kev_date_added":null,"published":"2026-06-18"},{"cvss_score":8.4,"headline":"[Eclipse Theia] Indirect Prompt Injection via Auto-Loaded Workspace Prompt Template Files in AI Chat","id":"CVE-2026-46580","kev_date_added":null,"published":"2026-06-18"}],"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":["The Eclipse Foundation"]},"summary":"Attackers can inject arbitrary JavaScript into the Eclipse Theia debug console due to missing HTML escaping, potentially executing code in the user's context.","url":"https://insights.sbomify.com/CVE-2021-28161/"}
