Litecoin discloses zero-day vulnerability causing DoS attacks and abnormal MWEB transactions, issue now fixed

Techub News, Litecoin has disclosed that a recent zero-day vulnerability led to a DoS attack, affecting the operation of major mining pools. Mining nodes that were not updated in time allowed an invalid MWEB (MimbleWimble Extension Block) transaction to be executed, enabling the relevant tokens to be withdrawn to a third-party DEX. The Litecoin network rolled back these invalid transactions through a reorganization (reorg) of 13 blocks, confirming that they would not be included in the main chain. All valid transactions during this period were unaffected. The vulnerability has now been fully fixed, and the network is operating normally.
