Emergency Revocation Results in Permanent Token Lock

casinocompiler

Summary

The RAACReleaseOrchestrator::emergencyRevoke() function, designed for emergency revocation of vested tokens, mistakenly transfers the tokens to itself (address(this)) without any mechanism to recover or redistribute these tokens, resulting in a permanent reduction of the token supply.

Vulnerability Details

The issue exists in the emergencyRevoke function:

function emergencyRevoke(address beneficiary) external onlyRole(EMERGENCY_ROLE) {
VestingSchedule storage schedule = vestingSchedules[beneficiary];
if (!schedule.initialized) revert NoVestingSchedule();
uint256 unreleasedAmount = schedule.totalAmount - schedule.releasedAmount;
delete vestingSchedules[beneficiary];
if (unreleasedAmount > 0) {
@> raacToken.transfer(address(this), unreleasedAmount);
emit EmergencyWithdraw(beneficiary, unreleasedAmount);
}
emit VestingScheduleRevoked(beneficiary);
}

The contract has predefined token allocations for different categories:

categoryAllocations[TEAM_CATEGORY] = 18_000_000 ether; // 18%
categoryAllocations[ADVISOR_CATEGORY] = 10_300_000 ether; // 10.3%
categoryAllocations[TREASURY_CATEGORY] = 5_000_000 ether; // 5%
categoryAllocations[PRIVATE_SALE_CATEGORY] = 10_000_000 ether;// 10%
categoryAllocations[PUBLIC_SALE_CATEGORY] = 15_000_000 ether; // 15%
categoryAllocations[LIQUIDITY_CATEGORY] = 6_800_000 ether; // 6.8%

When emergencyRevoke is called, it calculates the unreleased tokens and transfers them to the contract itself. However, the contract lacks any functionality to transfer these tokens out or redistribute them, effectively locking them permanently.

Impact

High:

  • Tokens are permanently locked, reducing the total circulating supply

  • The intended token distribution percentages are disrupted

Likelihood

Low - Emergency revokes do not happen regularly.

Recommendations

Implement a recovery mechanism for locked tokens
