An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-34422 and fix it if it is affected.\n\nWhat it is: CVE-2021-34422 is a high-severity path traversal vulnerability in Zoom Video Communications Inc Keybase Client for Windows, published on 11 Nov 2021. An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-34422 in the wild and no public exploit code.\n\nAffected product: Zoom Video Communications Inc Keybase Client for Windows. 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-2021-34422/ (Markdown: https://insights.sbomify.com/CVE-2021-34422/index.md)","id":"CVE-2021-34422","markdown":"https://insights.sbomify.com/CVE-2021-34422/index.md","name":"CVE-2021-34422","record":{"aliases":["GHSA-rr44-rmpx-9h3q"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Keybase Client","requires_auth":"none","summary":"A path traversal flaw in Keybase Client for Windows allows attackers to execute arbitrary code via crafted filenames in shared folders.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Zoom","cpe":[{"product":"keybase","vendor":"keybase"}],"cvss":{"score":7.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"The Keybase Client for Windows before version 5.7.0 contains a path traversal vulnerability when checking the name of a file uploaded to a team folder.
