CryptoWorld News reports that Wu said Litecoin has announced that its Mimblewimble Extension Block (MWEB) privacy layer has a zero-day vulnerability, causing some unupdated nodes to validate invalid transactions and trigger a DOS attack against mining pools. The attacker used this to transfer funds to third-party DEXs. Subsequently, the network reorganized approximately 13 blocks to roll back the invalid transactions. Normal transactions were unaffected. The vulnerability has now been fixed, and the network has resumed normal operation.
