CVE-2026-18652rapid7velociraptor
EPSS score0.27%
Velociraptor allows reading Stacked result sets from the GUI. Velociraptor's multi-tenant design stores sub orgs within the datastore directory. The path requested by the GUI is not correctly checked against the prefix deny list, allowing result sets to read from denied prefixes.
In particular, a user with read access to the root org can access result sets from child orgs.CVE-2026-18972rapid7velociraptorEPSS score0.35%
An authenticated attacker can spoof another GUI user's identity by sending their request with the custom header \"Grpc-Metadata-USER\". This can lead to an account takeover attack from a user with low privileges to administrator.CVE-2026-18348rapid7velociraptorEPSS score0.34%
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.CVE-2026-18640rapid7velociraptorEPSS score0.43%
The NewNotebook API does not sufficiently sanitize its parameters allowing an authenticated user with NOTEBOOK_EDIT permission to write the notebook record outside the org's data store directory. The file written must have an extension of ".json.db" but can otherwise overwrite other metadata files (such as ACL records, hunts etc). This can corrupt these files and cause data corruption.CVE-2026-18636rapid7velociraptorEPSS score0.40%
The Velociraptor gRPC API has a VFSGetBuffer endpoint which allows reading files from the datastore. To prevent users from reading sensitive files or accessing other orgs, the requested path is prefix checked against a list of denied prefixes. This prefix check can be bypassed allowing a user to access usually denied files. If the user has read permission in the ROOT org, this allows access to other orgs, in which the user may not have permission.CVE-2026-18635rapid7velociraptorEPSS score0.46%
Velociraptor's VQL has a query() plugin which allows running a VQL query in a different org or user context. To be able to run as a different user, the calling user needs to have the IMPERSONATE permission (usually only given to administrators). Velociraptor versions prior to 0.77.2 evaluate this permission against the caller's org instead of against the target org.
This allows an administrator in one org to impersonate another user in another org, in which they may not have the IMPERSONATE permission.CVE-2026-18638rapid7velociraptorEPSS score0.41%
Any authenticated Velociraptor user — including one holding only the readerrole — can terminate the entire server process with a single request, by calling SetPassword with a username that does not exist.CVE-2026-5329rapid7velociraptorEPSS score0.64%
Rapid7 Velociraptor versions prior to 0.76.2 contain an improper input validation vulnerability in the client monitoring message handler on the Velociraptor server (primarily Linux) that allows an authenticated remote attacker to write to arbitrary internal server queues via a crafted monitoring message with a malicious queue name. The server handler that receives client monitoring messages does not sufficiently validate the queue name supplied by the client, allowing a rogue client to write arbitrary messages to privileged internal queues. This may lead to remote code execution on the Velociraptor server. Rapid7 Hosted Velociraptor instances are not affected by this vulnerability.CVE-2026-64954rapid7velociraptorEPSS score0.31%
Velociraptor allows scheduling new collections via VQL queries in notebooks. For a user to schedule a new collection, they require the COLLECT_CLIENT permission. However, this is not enforced when the user can run a VQL query which resets the authorization provider.
This allows a user who can run arbitrary VQL (usually with the "analyst" role) to launch new collections (usually requires the "investigator" role). This vulnerability is an escalation from an analyst to investigator role.CVE-2026-64951rapid7velociraptorEPSS score0.28%
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.
The problem is a Divide by Zero bug in the ShouldPadFile() function.CVE-2026-64955rapid7velociraptorEPSS score0.36%
When Microsoft Excel imports a CSV file, it executes cells beginning with certain characters as formulas, giving such CSV files arbitrary execution.
Velociraptor fails to sanitize such cells when exporting to CSV from various places such as the GUI, offline collector or data exports.
It 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. However, since this is such a common use case for Velociraptor we decided to highlight it in an advisory.CVE-2026-64952rapid7velociraptorEPSS score0.30%
The hunt_delete() VQL function allows deleting hunts.
Velociraptor misapplied the permission check requiring only COLLECT_CLIENT (usually assigned to the "investigator" role) instead of the "DELETE_RESULTS" permission (usually only assigned to "administrators").CVE-2026-15371rapid7velociraptorEPSS score0.37%
Velociraptor's web GUI allows specifying a custom type for columns in tables. The URL type takes the cell value and forms a URL which can be clicked in the GUI.The code does not limit the schemes allowed in this URL , allowing an attacker to specify a JavaScript scheme exposing the user to XSS.CVE-2026-78412rapid7velociraptorEPSS score0.22%
Velociraptor's WatchEvent gRPC API can specify the OrgId of the org from which events should be streamed. The server checks the API permissions against the caller's Org instead of the requested Org. This allows a user with API access in one org to read events from another org for which they have no access.CVE-2026-78411rapid7velociraptorEPSS score0.17%
Velociraptor's SetClientMetadata used the wrong permission check to enforce setting metadata on the server. This allows a user with LABEL_CLIENTS permission to update the server metadata.
Server metadata is often used to store site wide configuration data that should only be updated by the server admin.CVE-2026-78413rapid7velociraptorEPSS score0.16%
Velociraptor allows collection of VQL queries packaged into Artifacts from endpoints. These artifacts can be used to do anything and usually run with elevated permissions. To limit access to some dangerous artifact, Velociraptor allows for those to require high permissions like EXECVE to launch.
The `Windows.Sysinternals.SysmonLogForward` is a monitoring artifact used to forward sysmon events to the server. The artifact allows the user to specify an arbitrary binary path as a parameter, and did not enforce an additional required permission, allowing users with COLLECT_CLIENT permissions (normally given by the "Investigator" role) to collect it from endpoints and run a different binary program than the installed sysmon binary.
To successfully exploit this vulnerability the user must already have access to collect artifacts from the endpoint (i.e. have the COLLECT_CLIENT given typically by the "Investigator" role).CVE-2026-6290www.velocidex.com/golangvelociraptor+1EPSS score0.39%
Velociraptor versions prior to 0.76.3 contain a vulnerability in the query() plugin which allows access to all orgs with the user's current ACL token. This allows an authenticated GUI user with access in one org, to use the query() plugin, in a notebook cell, to run VQL queries on other orgs which they may not have access to. The user's permissions in the other org are
the same as the permissions they have in the org containing the notebook.CVE-2026-6863www.velocidex.com/golangvelociraptor+1EPSS score0.40%
Velociraptor versions prior to 0.76.4 contain a cross organization authorization bypass in the HTTP API. A user with only the reader role in the root organization (the lowest authenticated role, holding only READ_RESULTS permission ) can issue a single authenticated HTTP GET that can read any files from other orgs - even if they have no explicit permissions in the target org.
However, the problem does not occur in reverse - a user with read access to a sub org is unable to read from other org or the root org.CVE-2026-6948rapid7velociraptorEPSS score0.44%
Velociraptor versions prior to 0.76.4 contain a resource exhaustion vulnerability in the server's agent control channel.
This allows a compromised or rogue Velociraptor client to crash the server via out-of-memory (OOM) by sending crafted messages through the normal client communication channel.CVE-2026-8795rapid7velociraptorEPSS score0.21%
A YAML injection vulnerability exists in the Windows.Collectors.Remapping artifact of Rapid7 Velociraptor before version 0.76.6. The hostname field in client_info.json inside a collection ZIP is inserted into a YAML template via Go's text/template without escaping. An attacker providing a crafted collection ZIP can leverage literal double quotes and newlines in the hostname to break out of the YAML quoted string and inject a new mount remapping entry. When an analyst applies the generated remapping file with --remap, arbitrary VQL executes on their machine with NullACLManager (all permissions granted, unsandboxed).
