Miggo AIRoot Cause Analysis

The vulnerability stems from the global variable jwtSecretKey in logic/jwts.go being initialized with a static value (BytesOverTheWire). Both CreateJWT and CreateUserJWT functions used this hard-coded key to sign JWTs. The patch replaced the hard-coded value with a dynamically generated secret (via SetJWTSecret), confirming these functions were vulnerable due to their dependency on the static key. The functions' direct use of jwtSecretKey for cryptographic operations aligns with CWE-321 and CWE-798.
