EPSS

• CVE-2026-6863: 0.24% estimated exploitation activity in the next 30 days; percentile 14.63 (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 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 READRESULTS 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.

# Patch Next advisory brief: CVE-2026-6863

Advisory: Velocidex Velociraptor has an Incorrect Authorization issue
IDs: CVE-2026-6863, GHSA-2v93-vp82-cjv8
Record: https://patchnext.com/advisories/cve-2026-6863 (revision 1, source checked 26 Oct 2026, 15:20 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.8)
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 0.76.4. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go www.velocidex.com/golang/velociraptor: affected < 0.76.4; fixed in 0.76.4

## 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-2v93-vp82-cjv8 (GitHub-reviewed advisory GHSA-2v93-vp82-cjv8 lists affected ranges: Go www.velocidex.com/golang/velociraptor >=0 <0.76.4)
