## What is CVE-2026-6863?

CVE-2026-6863 is a medium-severity missing authorization vulnerability in Rapid7 Velociraptor, published on 6 May 2026. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

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.

Weakness: CWE-863 (Incorrect Authorization)

What it is: CVE-2026-6863 is a medium-severity missing authorization vulnerability in Rapid7 Velociraptor, published on 6 May 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-6863 in the wild and no public exploit code.

Affected packages and fixed versions:
- www.velocidex.com/golang/velociraptor (Go): affected all versions; fixed in 0.76.4
- www.velocidex.com/golang/velociraptor (Go): affected all versions; fixed in 0.76.4
- www.velocidex.com/golang/velociraptor (Go): affected all versions; fixed in 0.76.4

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
