vulnerability
ANKR and Stader's liquid staking protocols for BSC are vulnerable to MEV-based sandwich attacks on the updateRatio() reward distribution function, allowing attackers to steal rewards from the pool by depositing before reward updates and withdrawing after, without actually staking their funds for the required period. The vulnerability enables attackers to capture a proportional share of protocol rewards through timing manipulation and DeFi market exits.
