Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Authentication Bypass: Signature validation used the provider's address instead of the quote's liquidity provider address, allowing an attacker to authenticate as a different LP.
Signature Validation Bypass: Missing chain ID validation before signing allows cross-chain replay attacks, where a quote signed for one chain is replayed on another.
Prototype Pollution: Handlebars before 4.7.9 had a critical prototype pollution vulnerability enabling arbitrary code execution; fixed by dependency upgrade.
