CVE-2026-55658: CWE-862: Missing Authorization in 1Hive gardens-v2
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.

Technical Analysis
Gardens v2 enables communities to manage governance pools with customizable voting. In versions up to and including commit 3e595f3, when a streaming proposal is funded, pool funds are moved into a StreamingEscrow contract to back a Superfluid constant flow agreement. If the proposal is canceled, the escrow's GDA member units are zeroed but the escrowed balance is not reclaimed. The permissionless claim() function allows the beneficiary, chosen by the proposal submitter, to receive the entire escrow balance, including the pool-funded buffer. The only mechanism to return escrow funds to the pool is drainToStrategy, which is restricted to strategy roles and only triggered by dispute reject rulings, not by cancel or natural completion. This results in unauthorized fund transfer due to missing authorization checks.
Potential Impact
An attacker with permission to submit proposals can specify a beneficiary address to claim escrowed funds improperly after proposal cancellation, causing unauthorized transfer of pool funds. This impacts the integrity of the governance pool's funds, potentially leading to financial loss or misuse of community resources. There is no impact on confidentiality or availability reported.
Mitigation Recommendations
At the time of publication, no official patch or remediation is available. Users should monitor vendor advisories for updates. Until a fix is released, avoid submitting proposals that could trigger this issue or restrict proposal submission permissions to trusted parties to reduce risk.
