⚠️ Risk & Real-World Impact
Worst Case
Attackers could manipulate cryptographic operations to bypass authentication, tamper with encrypted data, or potentially execute arbitrary code through crafted input.
Likely Case
Data integrity compromise where attackers can manipulate input to cryptographic functions, potentially leading to incorrect encryption/decryption results or bypassing security checks.
If Mitigated
Limited impact with proper input validation and sanitization in place, though the underlying vulnerability remains exploitable.
🎯 Exploit Status
Exploitation requires the attacker to provide malicious input to vulnerable cryptographic functions.
🛠️ Fix & Mitigation
