Bitcoin Core tiết lộ lỗ hổng ảnh hưởng đến lưu lượng Tor

The Huoxing Finance report states that Bitcoin News posted on X platform, revealing a vulnerability in Bitcoin Core: when service providers bundle Bitcoin Core with Tor, incoming Tor traffic is treated as local traffic, causing nodes with whitelist settings enabled to relax spam and privacy restrictions toward external nodes, thereby granting them a "trusted" status across thousands of nodes. The fix for this vulnerability was released in October 2025, but Bitcoin Core only disclosed the details two weeks after ending support for the 29.x series. Additionally, another high-severity vulnerability could prevent mining nodes from constructing valid blocks until they are restarted; no related attacks have been reported, and nodes without whitelist settings are unaffected.
