{"id":"CVE-2026-18348","summary":"Velociraptor NETWORK ACL bypass via upload_azure / upload_sftp / upload_smb VQL plugins","details":"Missing authorization check in the upload_azure, upload_sftp, and upload_smb VQL plugins allows an authenticated analyst-role user can initiate attacker-controlled outbound network connections from the Velociraptor server, bypassing the NETWORK ACL permission boundary. This enables internal network reconnaissance via port oracle and potential data exfiltration to external endpoints.","modified":"2026-08-30T03:30:17.240131571Z","published":"2026-08-11T05:37:11.333Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/18xxx/CVE-2026-18348.json","cna_assigner":"rapid7","cwe_ids":["CWE-863"]},"references":[{"type":"WEB","url":"https://github.com/Velocidex/velociraptor/"},{"type":"ADVISORY","url":"http://docs.velociraptor.app/announcements/advisories/cve-2026-18348/"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/18xxx/CVE-2026-18348.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-18348"},{"type":"FIX","url":"https://github.com/Velocidex/velociraptor/commit/48824fb51a2bdba832abc281e719ecbed74736df"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/velocidex/velociraptor","events":[{"introduced":"0"},{"fixed":"48824fb51a2bdba832abc281e719ecbed74736df"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"0.77.2"}]}}],"versions":["v0.76.1-rc1","v0.75","v0.74","v0.73","v0.72","v0.7.0","v0.7.0-rc1","v0.6.8-rc1","v0.6.7-rc1","v0.6.4-rc1","v0.6.3-rc1","v0.6.2-rc1","v0.6.1-rc1","v0.6.0-rc1","v0.5.9-rc1","v0.5.8-rc1","v0.5.7","v0.5.6","v0.5.5-1","v0.5.5","v0.5.4","v0.5.3","v0.5.2","v0.5.1","v0.5.0","v0.4.9","v0.4.8","v0.4.7","v0.4.6","v0.4.5","v0.4.4","v0.4.3","v0.4.2","v0.4.1","v0.4.0","v0.3.9","v0.3.8","v0.3.7","v0.3.6","v0.3.5","v0.3.4","v0.3.3","v0.3.2","v0.3.1","v0.3.0","0.2.9","0.2.8","0.2.7","0.2.6","0.2.5","0.2.4","0.2.3","0.2.2","0.2.1","v0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-18348.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:L/I:N/A:N"}]}
