Root Cause:
The mintProfile function performs an external call via _safeMint (which may trigger a callback on the recipient) before updating internal state variables (such as recording the token ID in profileToToken and storing profile metadata). This violates the Checks–Effects–Interactions pattern.

Impact:
A malicious receiver contract could exploit the reentrancy possibility to call back into mintProfile (or other functions like burnProfile/blockProfile) before state changes are finalized. This might lead to inconsistent states or unintended multiple profile creations.

Recommendation:
Restructure the function to update all internal state (effects) before performing any external calls (interactions). Alternatively, add a reentrancy guard (using a modifier like OpenZeppelin’s nonReentrant) to protect the function against recursive calls.
