Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Cryptographic Weakness: The key derivation process previously relied on a static salt and low iteration counts, making password-based key generation susceptible to offline brute-force attacks. Future cryptographic changes must maintain unique, context-specific salts (like the room name) and high iteration counts.
Cryptographic Weakness: A lack of session key rotation compromised historical message confidentiality if a long-term key was exposed. Ensuring robust session key rotation during decryption phases is critical to preserving forward secrecy.
