CVE-2026-53924: CWE-284: Improper Access Control 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. Prior to 0xc9d4e0dacd937364793278180551e59d93cd43f9, StreamingEscrow.claim() correctly rejects withdrawals while an escrow is disputed, but the permissionless syncOutflow() path performs the same excess-balance transfer without checking disputed. After a streaming proposal is challenged, anyone can call syncOutflow() to transfer escrowed SuperTokens to the proposal beneficiary while the dispute is pending. If the proposal is later rejected, those tokens cannot be recovered by drainToStrategy(). This issue has been patched in 0xc9d4e0dacd937364793278180551e59d93cd43f9.

Technical Analysis
Gardens v2 allows communities to manage governance pools with customizable voting. Before commit 0xc9d4e0dacd937364793278180551e59d93cd43f9, the StreamingEscrow.claim() method correctly prevented withdrawals during disputes, but the permissionless syncOutflow() method did not check for disputes and allowed transferring escrowed SuperTokens to the proposal beneficiary while a dispute was active. If the proposal was later rejected, those tokens could not be recovered by drainToStrategy(). This improper access control flaw (CWE-284) was fixed in the referenced commit.
Potential Impact
An attacker or any user can invoke syncOutflow() to transfer escrowed tokens to a proposal beneficiary during an active dispute, potentially causing loss of tokens that cannot be recovered if the proposal is rejected. This undermines the integrity of the governance escrow mechanism and may lead to unauthorized token transfers.
Mitigation Recommendations
The issue has been patched in commit 0xc9d4e0dacd937364793278180551e59d93cd43f9. Users and operators of gardens-v2 should update to the fixed version incorporating this commit. No other mitigation guidance is provided, and patch status is not explicitly stated beyond the commit reference, so verify with the vendor for official releases.
