Incorrect workingSupply Adjustment in Boost Delegation

oxelmiguel

Summary

The BoostController::updateUserBoost function is responsible for recalculating and updating the boost for a user in a specific pool. However, there is a issue where workingSupply is directly set to newBoost, rather than being adjusted incrementally. This could result in incorrect reward calculations or governance weight distributions.

Vulnerability Details

In the function BoostController::updateUserBoost, the workingSupply is set directly to newBoost, leading to incorrect calculations of active boosts in a pool. Unlike totalBoost, which is updated incrementally, workingSupply is being replaced outright, which does not correctly account for cumulative adjustments from multiple users updating their boosts.

Affected Code:

https://github.com/Cyfrin/2025-02-raac/blob/89ccb062e2b175374d40d824263a4c0b601bcb7f/contracts/core/governance/boost/BoostController.sol#L198

function updateUserBoost(address user, address pool) external override nonReentrant whenNotPaused {
if (paused()) revert EmergencyPaused();
if (user == address(0)) revert InvalidPool();
if (!supportedPools[pool]) revert PoolNotSupported();
UserBoost storage userBoost = userBoosts[user][pool];
PoolBoost storage poolBoost = poolBoosts[pool];
uint256 oldBoost = userBoost.amount;
// Calculate new boost based on current veToken balance
uint256 newBoost = _calculateBoost(user, pool, 10000); // Base amount
userBoost.amount = newBoost;
userBoost.lastUpdateTime = block.timestamp;
// Update pool totals safely
if (newBoost >= oldBoost) {
poolBoost.totalBoost = poolBoost.totalBoost + (newBoost - oldBoost);
} else {
poolBoost.totalBoost = poolBoost.totalBoost - (oldBoost - newBoost);
}
// Incorrect adjustment of workingSupply
poolBoost.workingSupply = newBoost; // Should be incrementally adjusted
poolBoost.lastUpdateTime = block.timestamp;
emit BoostUpdated(user, pool, newBoost);
emit PoolBoostUpdated(pool, poolBoost.totalBoost, poolBoost.workingSupply);
}

Impact

This issue lead to inaccurate tracking of the working supply in a pool, potentially affecting:

  • Reward distributions, where incorrect working supply values result in misallocated incentives.

  • Governance weight calculations, where influence is incorrectly distributed due to boost mismanagement.

  • Pool performance metrics, which might not reflect the actual number of active boosted users correctly.

Tools Used

  • Manual code review

Recommendations

  1. Incrementally Adjust workingSupply Like totalBoost:
    Modify workingSupply to be adjusted incrementally, rather than being set directly:

    if (newBoost >= oldBoost) {
    poolBoost.workingSupply += (newBoost - oldBoost);
    } else {
    poolBoost.workingSupply -= (oldBoost - newBoost);
    }

BoostController::updateUserBoost overwrites workingSupply with single user's boost value instead of accumulating, breaking reward multipliers and allowing last updater to capture all benefits
