Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-64951 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-2026-64951/ (Markdown: https://insights.sbomify.com/CVE-2026-64951/index.md)","id":"CVE-2026-64951","markdown":"https://insights.sbomify.com/CVE-2026-64951/index.md","name":"CVE-2026-64951","record":{"aliases":["GHSA-frg5-mq2m-h39j"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Velociraptor DFIR server","requires_auth":"low_privilege","summary":"A malicious client can crash the Velociraptor server by uploading a malformed sparse file that triggers a divide-by-zero panic during GUI expansion.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"rapid7","cpe":[],"cvss":{"score":3.5,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-369","name":"Divide By Zero"}],"description":"A rogue Velociraptor client can upload a malformed sparse file such that if the GUI attempts to expand the file, a panic occurs which may crash the server process.\n\nThe problem is a Divide by Zero bug in the ShouldPadFile() function.","ecosystems":[],"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":"Velociraptor DoS triggered by Divide by Zero panic","id":"CVE-2026-64951","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Velociraptor Hunt Deletion With Insufficient Permission Check","id":"CVE-2026-64952"},"packages":[],"prev":{"headline":"Stored Cross-Site Scripting via Directory Name in File Manager Create Directory","id":"CVE-2026-64950"},"products":["Velociraptor"],"published":"2026-08-12","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"partial"},"state":"PUBLISHED","updated":"2026-08-12","vendors":["Rapid7"]},"summary":"A malicious client can crash the Velociraptor server by uploading a malformed sparse file that triggers a divide-by-zero panic during GUI expansion.","url":"https://insights.sbomify.com/CVE-2026-64951/"}
