Public incident records describe a flash-loan-assisted protocol-logic exploit, but do not provide enough source-backed technical detail to identify the precise vulnerable function or validation failure.

How it happened

Available incident records consistently identify a flash-loan-assisted exploit against Wise Lending V2 that affected Ethereum and Arbitrum and resulted in about $66,000 in losses. Public reporting does not include a technical post-mortem that names a specific function or invariant, so the details here stop at the reported flash-loan and protocol-logic facts.
