  "title": "Cross-shard validation flaws in tari_consensus and tari_ootle_storage",
  "summary": "The affected crates process cross-shard transaction pledges without cryptographically binding pledged state values to the associated proof, and can retain evidence for locks that were requested but not granted. A Byzantine validator acting as a relevant shard-group proposer or leader may cause execution using altered pledged state or have a transaction accepted despite a lock conflict; multi-shard transaction processing is a prerequisite.",
  "mitigation": "Restrict or suspend multi-shard transaction processing where operationally feasible, and tightly control validator and proposer membership. Monitor upstream for a corrected release and upgrade both affected crates when one is published.",
