Signature Malleability
Signature malleability is a vulnerability where an attacker can change the signature of a transaction without invalidating it, even though they cannot change the transaction data itself. Because the signature is still valid, the transaction will still be processed by the network.
However, this can cause issues with transaction tracking and the indexing of transactions by their hash. In some protocols, this can be exploited to trick users or services that rely on the transaction hash to identify a payment.
Most modern blockchains have implemented upgrades to fix this issue by making signatures non-malleable. Understanding this vulnerability is important for developers building applications on top of existing blockchain protocols.
