Found in the 0.E security review (Minor). Only the storage key is length-validated (try_into::<[u8;32]>); WORM/ledger keys loaded from the vault are not. Not exploitable (HMAC accepts any length; keys always minted at 32 bytes) but a truncated stored key would be used silently. Add explicit length validation.
