CVE-2026-6863 HTTP Filestore Endpoints Misapply Permissions Across Organizations
Publishedon 2026-04-28
CVSS · MEDIUM · 6.8 ⁄10 · CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:N
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.
Problem:
CWE-863: Improper Authorization
CWE-863
Impact:
CAPEC-114: Authentication Abuse
