ChainCatcher news, DefiLlama founder 0xngmi tweeted that the NFT market Foundation has a vulnerability in its NFT contract that allows the Foundation team to destroy almost all NFTs minted on its platform. The Foundation's collection contract uses a proxy forwarding model to save on deployment gas, which means that all collections call a single contract to use its code without issue, and the Foundation's collection has a feature that allows creators to destroy it without an NFT. Currently, the contract ownership of the Foundation team is held by 2 out of 6 multi-signatures.

0xngmi stated that a fix could be implemented by minting 1 NFT in the implementation contract and then transferring it to a burn address to remove this backdoor, but he disclosed this issue to the Foundation 6 months ago and it has not been fixed to date. (Source link)
