Briefings

Bitcoin Core revealed a critical vulnerability allowing nodes to trust any stranger on Tor, which was fixed in October 2025 but hidden until Tuesday. The flaw enabled a high-severity bug that could halt block production until a restart, though specific impact on the network remains unquantified.

Key points

• Bitcoin Core contained a vulnerability allowing nodes to trust any stranger on Tor, which was fixed in October 2025.
• A high-severity bug could stop a miner from producing blocks until someone restarted the node.

Context

This finding addresses a critical security gap in Bitcoin Core's Tor integration, where nodes could potentially trust strangers, potentially compromising network integrity.

Limitations

The evidence is limited to the description of the vulnerability and its fix; specific impact on the network, number of affected nodes, or precise date of the high-severity bug's occurrence are not provided.
