CVE-2026-53924Network attack vector

Escrow token diversion via unchecked disputed state

Published Sep 3, 2026 · Updated Sep 3, 2026

Improper access control in 1Hive Gardens v2 allows remote attackers to divert disputed escrow tokens through the permissionless syncOutflow() path. StreamingEscrow.syncOutflow() transfers excess SuperToken balances to the proposal beneficiary without checking the escrow's disputed state, unlike claim(). A streaming proposal must already be challenged; if it is later rejected, drainToStrategy() cannot recover the transferred tokens.
