Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Cryptographic Flaw: Improper Fiat-Shamir transcript construction can allow proof forgery; the fix added domain separation by including all necessary values in challenges.
Cryptographic Implementation: Commitment hashing in the transcript was vulnerable to malleability or collision attacks; the fix separated commitment hashing into a dedicated 'hcom' transcript.
Input Validation: Missing length check on public inputs could allow malformed input processing; the fix added a length check before use.
