🔹 State: 🟢 Resolved
🔹 Disclosed: September 17, 2026, 5:38pm (UTC)
🐞 Source: HackerOne

The ZMQ `get_output_distribution` RPC was vulnerable to a memory exhaustion denial-of-service attack. The method accepted an unbounded `amounts` array and returned a separate distribution for each entry, allowing a small request to expand into a very large response by repeatedly including the amount `0`. The issue was also reachable with `--restricted-zmq-rpc` because ZMQ lacked the stricter validation applied by…
