Severity by source
AV:N/AC:H/PR:L/UI:R/S:C/C:H/I:H/A:N
Chained attack requires low-privileged NOTEBOOK_EDITOR account (PR:L), admin restore action (UI:R), and specific backup timing (AC:H); scope change to server-level VQL execution yields C:H/I:H.

Velociraptor allows for the creation of notebook backups in its default enabled daily backup feature. When Velociraptor restores the backup, the notebook cell content is interpolated into a template with no ACL checks. This allows a malicious user with NOTEBOOK_EDITOR permission to plant a VQL query which will be evaluated at elevated permissions if the notebook's backup is subsequently restored.
AnalysisAI
Template injection in Velociraptor's notebook backup restoration pipeline allows a low-privileged NOTEBOOK_EDITOR user to execute arbitrary VQL queries at elevated server-level permissions. The daily backup feature - enabled by default - captures notebook cell content verbatim; when an administrator later restores the backup, that content is interpolated into a Go template without ACL enforcement, breaking the privilege boundary between analyst and server roles. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must hold an active Velociraptor account with the NOTEBOOK_EDITOR permission - a non-default role that must be explicitly granted by an administrator. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:N/AC:H/PR:L/UI:R/S:C/C:H/I:H/A:N, score 7.7) accurately reflects the multi-step nature of this attack: low privilege to plant the payload, high complexity from the required chaining, mandatory user interaction from an administrator performing the restore, and a scope change representing the privilege boundary break. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the fix from GitHub pull request #4967 (https://github.com/Velocidex/velociraptor/pull/4967) once it is merged into an official tagged release - consult the vendor advisory at http://docs.velociraptor.app/announcements/advisories/cve-2026-19584/ for the confirmed patched version, which was not specified in the input data. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, verify whether Velociraptor is deployed in your environment and identify the current version; document all systems running affected versions and inventory all users with NOTEBOOK_EDITOR permissions. …
