CVE-2026-93596Public exploitNetwork attack vectorHinoki check available

Protected graph modification via unbound async workers

Published Sep 18, 2026 · Updated Sep 18, 2026

Missing authorization in ArcadeDB before 26.9.1 allows remote authenticated users to modify protected graph adjacency through batch imports. The parallel edge-connect phase dispatches writes to DatabaseAsyncTransaction workers without the authenticated principal, so LocalDatabase.checkPermissionsOnFile returns early and skips per-type ACLs. Exploitation requires database access, CREATE_RECORD on an edge type, denied create or update rights on a vertex type, and the default parallelFlush setting; successful requests durably append edges to protected vertices.
