CVE-2026-55658 Details
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.
A vulnerability exists in Gardens V2, specifically in the governance framework's streaming proposal mechanism. When a proposal is funded, pool funds are transferred into a 'StreamingEscrow' contract to support a Superfluid constant flow agreement. However, when a proposal is canceled, the escrow's balance is not properly reclaimed, allowing the entire escrow amount, including the pool-funded buffer, to be claimed by the proposal's beneficiary. This issue arises because the only function that can return funds to the pool is rarely invoked. As a result, pool funds are effectively drained without oversight.
To address this vulnerability, the 'cancelProposal' function should be modified to call 'drainToStrategy' before or after zeroing the GDA member units, returning any residual balance to the pool. Additionally, the 'claim' function should be restricted to prevent post-cancellation transfers to the beneficiary, or alternatively, maintain a non-zero reserved deposit floor while the escrow holds protocol-owned buffer.
