Security Advisories fixed in release 0.77.2

The Velociraptor project was lucky to receive a number of security advisories recently. A number of talented and experienced security researchers shared their findings and thorough reviews with our team.

We would like to extend our gratitude to the following researchers for responsibly sharing their findings:

  • Hamad Alghamdi
  • Itay Vardi
  • Mayank Rajput (https://github.com/hackelite01)
  • Leonardo Souza (anauaque)
  • Yuval Miller and Leon Kayaliev
  • Kris Kennaway (Datadog)
  • Tristan Madani (Talence Security)

There were a large number of advisories, the majority fell into some broad categories.

ACL, identity and permission issues

Velociraptor started off being a DFIR tool used by a small trusted team. As the project matured, it has developed enterprise security features:

  • Multi-tenancy - being able to isolate cases into separate orgs, all sharing the same server.
  • Multiple users and a discretional access control mechanism to separate and control users’ actions.

Although most users still use the tool within a small trusted team it is important to ensure that the user ACLs are properly enforced. The recent round of security reviews tackled the Velociraptor security model and assisted in locking down any bypasses.

The following vulnerabilities are examples where a malicious authenticated user of the Velociraptor GUI can exceed their allowed permissions.

  • CVE-2026-18348: Velociraptor NETWORK ACL bypass via upload_azure / upload_sftp / upload_smb VQL plugins
  • CVE-2026-18635: Velociraptor query plugin allows impersonation in other orgs
  • CVE-2026-18636: Velociraptor VFSGetBuffer API path deny list bypass
  • CVE-2026-18638: Velociraptor server crash via the SetPassword API
  • CVE-2026-18640: Velociraptor directory traversal via the NewNotebook API
  • CVE-2026-18972: Velociraptor authenticated identity-spoofing vulnerability
  • CVE-2026-18652: Velociraptor STACK Type Download Path Bypasses Denied Prefix Check
  • CVE-2026-18860: Velociraptor incorrect Org deletion permissions check
  • CVE-2026-64952: Velociraptor Hunt Deletion With Insufficient Permission Check
  • CVE-2026-64954: Velociraptor collect_client() Permissions Bypass

Stability and crashes

Other vulnerabilities identify bugs in parsing edge conditions leading to possible crashes.

  • CVE-2026-18638: Velociraptor server crash via the SetPassword API
  • CVE-2026-17535: Velociraptor Multiple Crashes in NTFS Parser when applied to invalid NTFS Volumes
  • CVE-2026-64951: Velociraptor DoS triggered by Divide by Zero panic

General improvements

The researchers have highlighted some design issues and helped to harden Velociraptor

  • CVE-2026-18639: Velociraptor OIDC Authenticator susceptible to email spoofing

    • Some OIDC providers allow users to spoof emails, making Velociraptor’s reliance of emails dangerous.

  • CVE-2026-64955: Velociraptor CSV Formula Injection in Export Pipeline

    • Some spreadsheet programs (e.g. MS Excel) treat CSV files as executable content allowing formulas to be run when loading CSV files.

Upgrade

To fix these issues and others, we recommend users upgrade to the latest 0.77.2 release. If you would rather not upgrade to the latest release, you can update to the latest build from the previous 0.76.7 release.
