CVE-2026-55658Gardens v2: StreamingEscrow buffer drains to the proposal beneficiary on cancel via the permissionless claim()
High 7.7
In plain English
A high-severity missing authorization in gardens-v2 from 1Hive. Proof-of-concept exploit code is public. The chance it is exploited in the next 30 days is estimated at 0.3% (higher than 23% of all known vulnerabilities).
Official description
Gardens v2 is a modular governance framework that enables communities to create and manage multiple governance pools with customizable parameters and voting mechanisms. In 3e595f3 and prior, when a streaming proposal is funded, the cluster of streaming contracts moves real pool funds into the proposal's StreamingEscrow to back the Superfluid constant flow agreement (the CFA deposit, plus a 0.5 percent margin). cancelProposal then zeroes the escrow's GDA member units but never reclaims that parked balance, and the permissionless claim() forwards the escrow's entire balance, including the pool funded buffer, to the beneficiary. The beneficiary is chosen by the proposal submitter and defaults to the submitter. The only path that returns escrow funds to the pool is drainToStrategy, which is onlyStrategy and is reached solely from the dispute reject ruling, never from cancel or natural completion. At time of publication, there are no publicly known patches.
