Cross-chain bridge unverified mint pattern

Wormhole's assessment for RD-F-106 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

Yes — this is THE canonical Wormhole attack vector; Feb 2022 exploit was exactly this pattern (120,000 wETH minted on Solana without valid ETH lock on Ethereum) | No current unverified-mint events identified; Guardian signing requirement (13/19) is the defense against this; signal requires cross-chain indexer monitoring | No current firing; signal is highest-priority for Wormhole-class bridge monitoring
