CVE-2026-40141Network attack vector

Authenticated data access via unneutralized query input

Published Jul 6, 2026 · Updated Jul 6, 2026

Query-logic injection in BeyondTrust Remote Support and Privileged Remote Access allows remote authenticated users to access unauthorized data. The web application component fails to neutralize special elements in certain user-supplied parameters before using them in data-query logic; BeyondTrust has not disclosed the parameters, handler, or query language. Reachability requires authentication, limited privileges, and specific account permissions, and the reported consequence is access to resources or data outside the account's authorization scope.
