  "title": "Shard-binding failure in tari_state_tree exclusion proofs",
  "summary": "`tari_state_tree`, `tari_ootle_storage`, and `tari_indexer_lib` are affected when an indexer verifies substate-absence proofs. A malicious validator able to provide substate RPC responses to an indexer can make a live substate appear absent, causing cached indexer data and wallet displays to omit live UTXOs or balances. The attacker needs to be a serving validator for the relevant indexer; on-chain state and spend validation are not affected.",
  "mitigation": "Treat absence responses from a single validator as untrusted, and independently corroborate them before caching or presenting them to wallets. No corrected release is recorded; restrict indexer RPC sources to trusted validators and monitor upstream for a patched version.",
