30-40:⚠️ Potential issue | 🟠 Major | ⚡ Quick winStop logging raw payload previews and serialize once.
On Line 33 and Line 35,
data.to_string()is still executed twice. Also, Line 40 logs raw payload content, which can expose sensitive fields.Suggested patch
- log::info!( - "[socket] event received: name={} data_bytes={}", - event_name, - data.to_string().len() - ); - let payload_json = data.to_string(); + let payload_json = data.to_string(); + log::info!( + "[socket] event received: name={} data_bytes={}", + event_name, + payload_json.len() + ); let preview_end = crate::openhuman::util::floor_char_boundary(&payload_json, 500); log::debug!( - "[socket] event payload: name={} data={}", + "[socket] event payload preview: name={} preview_bytes={} total_bytes={}", event_name, - &payload_json[..preview_end] + preview_end, + payload_json.len() );As per coding guidelines: “Never log secrets, raw JWTs, API keys, credentials, or full PII in debug logs; redact or omit sensitive fields.”

handle_sio_eventlogged incoming payloads with a naked byte slice:When the JSON serialization is ≥500 bytes and a multi-byte character (e.g. Cyrillic
'н') straddles byte 500, the core thread panicked (byte index 500 is not a char boundary). Real Sentry repro: WhatsApp ingest payload on Windows (OPENHUMAN-TAURI-KC).Solution
let payload_json = data.to_string();let preview_end = floor_char_boundary(&payload_json, 500);&payload_json[..preview_end]— never slices inside a codepoint.Submission Checklist
