  "title": "Unauthenticated decode-time memory exhaustion in tari_validator_node",
  "summary": "tari_validator_node validators process submitted transactions through an RPC path that decodes them before applying the transaction-size limit. An unauthenticated peer able to reach this RPC service can cause disproportionate memory consumption and potentially terminate the validator by submitting concurrent requests.",
  "mitigation": "Restrict submit_transaction RPC access to trusted peers and reduce max_simultaneous_sessions to limit concurrent decoding. Monitor validator memory usage and apply an upstream release containing a decode-time size or element-count limit when one is published.",
