Tokens Get Locked in RAACReleaseOrchestrator During Emergency Revoke

allamloqman

Summary :

The emergencyRevoke function in RAACReleaseOrchestrator transfers unvested tokens back to the contract itself (address(this)) without any mechanism to redistribute or manage these tokens.

Vulnerability Details :

the issue can appear here :

function emergencyRevoke(address beneficiary) external onlyRole(EMERGENCY_ROLE) {
VestingSchedule storage schedule = vestingSchedules[beneficiary];
uint256 unreleasedAmount = schedule.totalAmount - schedule.releasedAmount;
@> delete vestingSchedules[beneficiary];
if (unreleasedAmount > 0) {
@> raacToken.transfer(address(this), unreleasedAmount); // Tokens already in contract get transferred to itself
emit EmergencyWithdraw(beneficiary, unreleasedAmount);
}
}

so When emergencyRevoke is called:

delete vestingSchedules[beneficiary];
raacToken.transfer(address(this), unreleasedAmount);

The schedule is deleted but the categoryUsed amount remains unchanged.therefore For new vesting schedules:

function createVestingSchedule(...) {
uint256 newCategoryTotal = categoryUsed[category] + amount;
if (newCategoryTotal > categoryAllocations[category]) revert CategoryAllocationExceeded();
categoryUsed[category] = newCategoryTotal;
}
​


The categoryUsed tracking means:

  • Previous allocations still count against the category limit

  • New schedules must fit within remaining allocation

  • Revoked tokens can't be reused because their allocation remains counted

Impact :

tokens transferred to address(this) by emergencyRevoke are truly locked.

Tools Used :

Manuel review.
