Submission Judgement Published Reason: Non-acceptable severity
Assigned finding tags:
[Invalid] Use of `_mint` istead of `_safeMint`
The `fulfillMintRequest` function is external and anyone can call it. If the protocol uses `_safeMint` instead of `_mint`, this introduces a reentrancy risk. It is better to use `_mint` and the caller is responsible for being able to obtain the token.
