DeerFlow, published on 1 Apr 2026. 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-2026-34430 in the wild and no public exploit code.\n\nAffected product: Bytedance Inc. DeerFlow. 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-2026-34430/ (Markdown: https://insights.sbomify.com/CVE-2026-34430/index.md)","id":"CVE-2026-34430","markdown":"https://insights.sbomify.com/CVE-2026-34430/index.md","name":"CVE-2026-34430","record":{"aliases":["GHSA-gxx6-2vwg-3gc3"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution","data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"DeerFlow sandbox","requires_auth":"none","summary":"Attackers can escape the sandbox and execute arbitrary commands on the host by bypassing regex validation in the bash tool.","user_interaction":"required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"deerflow","vendor":"deerflow"}],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-184","name":"Incomplete List of Disallowed Inputs"}],"description":"ByteDance DeerFlow versions prior to commit 92c7a20 contain a sandbox escape vulnerability in bash tool handling that allows attackers to execute arbitrary commands on the host system by bypassing regex-based validation using shell features such as directory changes and relative paths.
