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.
