Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Access Control: instantWithdraw allows users to withdraw staked assets immediately; without a whitelist, any unauthorized user could drain funds or bypass withdrawal restrictions. The fix added a whitelist gate, indicating this is a critical entry point.
Access Control: redelegate moves staked assets to a different validator; without a whitelist on the destination, an attacker could redirect funds to a malicious validator or cause loss of control. The fix added a destination validator whitelist.
Access Control: delegateVoteTo moves voting power; without validation, an unauthorized user could delegate votes to arbitrary addresses, manipulating governance outcomes. The fix added validation of voting power movement.
