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-2026-60009 in the wild and no public exploit code.\n\nAffected product: Eclipse Theia. 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-2026-60009/ (Markdown: https://insights.sbomify.com/CVE-2026-60009/index.md)","id":"CVE-2026-60009","markdown":"https://insights.sbomify.com/CVE-2026-60009/index.md","name":"CVE-2026-60009","record":{"aliases":["GHSA-2mw2-h8hj-xpjg","GHSA-62f6-wcvg-54h3"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Eclipse Theia IDE","requires_auth":"none","summary":"Unauthenticated attackers can write arbitrary files via a cross-origin request, potentially achieving remote code execution in browser-based deployments.","user_interaction":"required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"eclipse","cpe":[{"product":"theia","vendor":"eclipse"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"},{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"},{"id":"CWE-73","name":"External Control of File Name or Path"},{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"In Eclipse Theia versions up to and including 1.73.1, the `@theia/filesystem` backend binds `POST /file-upload` in every filesystem-enabled deployment. The handler takes an attacker-supplied absolute path from the multipart `uri` field and calls `fs.move(tmp, target, { overwrite: true })` with no workspace confinement and no authentication. In browser (non-Electron) deployments the connection token is enforced only on WebSocket upgrades; the HTTP middleware in `@theia/core` re-issues the cookie and calls `next()` without rejecting tokenless HTTP requests. Because `multipart/form-data` is a CORS-safelisted request type, a cross-origin web page can trigger the write with no preflight and no credentials, resulting in an unauthenticated arbitrary file write outside the workspace to any absolute path the backend process can write. This can escalate to remote code execution, for example by overwriting a startup-executed file such as `~/.bashrc`. Electron mode uses a separate `ElectronSecurityToken` and is not affected via this path.","ecosystems":[],"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":"File upload in Eclipse Theia","id":"CVE-2026-60009","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"file_upload","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Gitea organization team policy bypass through repository API","id":"CVE-2026-60010"},"packages":[],"prev":{"headline":"Gitea Jupyter notebook UI redress through CSS class injection","id":"CVE-2026-60008"},"products":["Eclipse Theia"],"published":"2026-08-05","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":"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":"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-08-05","vendors":["Eclipse Foundation"]},"summary":"Unauthenticated attackers can write arbitrary files via a cross-origin request, potentially achieving remote code execution in browser-based deployments.","url":"https://insights.sbomify.com/CVE-2026-60009/"}
