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-2026-64955 in the wild and no public exploit code.\n\nAffected product: Rapid7 Velociraptor. 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-2026-64955/ (Markdown: https://insights.sbomify.com/CVE-2026-64955/index.md)","id":"CVE-2026-64955","markdown":"https://insights.sbomify.com/CVE-2026-64955/index.md","name":"CVE-2026-64955","record":{"aliases":["GHSA-x3cx-8mg8-hcv2"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Velociraptor DFIR tool","requires_auth":"none","summary":"Attackers can execute arbitrary code via CSV formula injection in Velociraptor exports when opened in Excel.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"rapid7","cpe":[],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-1236","name":"Improper Neutralization of Formula Elements in a CSV File"}],"description":"When Microsoft Excel imports a CSV file, it executes cells beginning with certain characters as formulas, giving such CSV files arbitrary execution. \n\nVelociraptor fails to sanitize such cells when exporting to CSV from various places such as the GUI, offline collector or data exports.\n\nIt is not clear if the vulnerability is actually in Microsoft Excel treating a CSV data file as executable content, or if Velociraptor should be sanitizing the data to prevent Excel from executing it.
