Abnormality Logic Map
HIGH SEVERITY

Logic Bomb / Backdoor Detected

Detected conditional branch dependent on environment variable ('DEBUG_MODE') leading to unauthenticated privilege escalation.

MEDIUM SEVERITY

Deprecated API Usage

Jwts.parser().setSigningKey() is deprecated and vulnerable to key confusion. Patched to parserBuilder().

INFORMATIONAL

Generic Exception Masking

Catching generic Exception masks runtime failures. Narrowed catch block to JwtException.
