Security researcher Merkle Bonsai documents a hybrid NFT vulnerability in Ocean Protocol where on-chain Data Description Objects (DDOs) can be modified to enable attacks, exploiting the protocol's reliance on modifiable on-chain data structures. The article discusses how these hybrid attacks work and references previous analysis of Ocean Protocol's design vulnerabilities.
A collection of blockchain security research and bug reports covering vulnerabilities in Oasys L2 blockchain, Eco's lockup contracts, and hybrid NFT attacks on Ocean Protocol. Multiple issues were identified and reported through Immunefi's bug bounty program.
