CVE-2026-82827
CriticalCVSS 9.8Summary
Hitachi Coding Software Suite up to version 3.3.0 uses a hard-coded cryptographic key for JWT signing, allowing an attacker to generate unauthorized Bearer tokens and exploit administrative functions.
Risk Assessment
The ability to generate valid JWT tokens allows an attacker to gain full control over the application, including administrative functions and sensitive data.
Recommendation
Immediately rotate the JWT key and implement secure key management and storage practices.
