EPSS

• CVE-2025-6264: 1.03% estimated exploitation activity in the next 30 days; percentile 63.74 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

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 Admin.Client.UpdateClientConfig is an artifact used to update the client's configuration. This artifact did not enforce an additional required permission, allowing users with COLLECTCLIENT permissions (normally given by the "Investigator" role) to collect it from endpoints and update the configuration. This can lead to arbitrary command execution and endpoint takeover. To successfully exploit this vulnerability the user must already have access to collect artifacts from the endpoint (i.e. have the COLLECTCLIENT given typically by the "Investigator' role).

# Patch Next advisory brief: CVE-2025-6264

Advisory: Velociraptor vulnerable to privilege escalation via UpdateConfig artifact
IDs: CVE-2025-6264, GHSA-gpfc-mph4-qm24
Record: https://patchnext.com/advisories/cve-2025-6264 (revision 1, source checked 26 Oct 2026, 15:13 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 4.7)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: www.velocidex.com/golang/velociraptor 0.74.3. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go www.velocidex.com/golang/velociraptor: affected < 0.74.3; fixed in 0.74.3

## Suggested inspection (read-only)
- Go www.velocidex.com/golang/velociraptor: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on www.velocidex.com/golang/velociraptor.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-gpfc-mph4-qm24 (GitHub-reviewed advisory GHSA-gpfc-mph4-qm24 lists affected ranges: Go www.velocidex.com/golang/velociraptor >=0 <0.74.3)
