Summary

A malicious validator can pass in incorrect score as it is not being sanitized.

Vulnerability Details

The protocol allows anyone to become a validator via LLMOracleRegistry::register function, it must be noted that there is no whitelisting mechanism or a way to remove oracles by the admins.

Malicious actor can register themselves as validator and fairly perform the Proof-of-Work nonce but pass an incorrect score in LLMOracleCoordinator::validate function as it lacks enough checks.

Such actors can actually keep on listening for others calling LLMOracleCoordinator::validate function and just pass a mean score. This allows them to actually not do any work other than calculating nonce.

Impact

Malicious validators would pass incorrect scores affecting the outcome
