Paused BaseGauge contract still allows staking and withdrawals

topstar

Summary

The BaseGauge contract allows users to stake and withdraw tokens without enforcing the whenNotPaused modifier. This means that even if the contract is paused, users can still perform these actions, potentially bypassing emergency controls.

Vulnerability Details

The stake and withdraw functions lack the whenNotPaused modifier from OpenZeppelin’s Pausable contract:

BaseGauge.sol

function stake(uint256 amount) external nonReentrant updateReward(msg.sender) {
function withdraw(uint256 amount) external nonReentrant updateReward(msg.sender) {

Since Pausable is implemented in the contract, it is expected that staking and withdrawing should be restricted when the contract is paused. However, without the whenNotPaused modifier, these functions remain accessible.

Impact

Users withdraw assets even if the contract is paused for security or governance reasons but cannot get accumulated rewards since getReward() has whenNotPaused modifier.

function getReward() external virtual nonReentrant whenNotPaused updateReward(msg.sender) {

Recommendations

Add whenNotPaused to both stake and withdraw functions.
