MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).

• Third-party content exposure detected (high risk: 0.90). The skill explicitly ingests SCP envelopes and fetches missing transaction sets and quorum sets from network peers (see PendingEnvelopes' mTxSetFetcher/mQuorumSetFetcher and outOfSyncRecovery's getMoreSCPState which asks random peers), i.e., untrusted third-party peer data that is parsed and fed into consensus processing and can change agent actions.

MEDIUM W009: Direct money access capability detected (payment gateways, crypto, banking).

• Direct money access detected (high risk: 1.00). The skill documents the Herder subsystem of Stellar Core — a subsystem explicitly responsible for collecting, building, broadcasting and nominating transaction sets into consensus (recvTransaction(), broadcastTx(), makeTxSetFromTransactions(), HerderSCPDriver::nominate(), TxSet/ApplicableTxSet handling, Soroban transaction queue, tx set fetchers, etc.). These are blockchain transaction-processing primitives (Stellar/Soroban) whose primary and explicit purpose is to process and externalize ledger transactions — i.e., moving assets on-chain. This is a specific crypto/blockchain financial capability, so it meets the "Direct Financial Execution" criterion.
