Bitcoin Core Discloses Tor and Mining Bugs: Who Was Affected and What Was Fixed?
Bitcoin Core has disclosed three previously patched security vulnerabilities, including a high-severity mining bug that could prevent affected nodes from generating block templates until restarted.
Another flaw exposed thousands of reachable mainnet nodes with certain Tor whitelist configurations to unintended trust permissions, while a third could delay block processing; fixes were released in October 2025.
The disclosures could increase scrutiny of Bitcoin's node infrastructure and reinforce the importance of software upgrades, although no successful exploitation or loss of funds was reported.
Bullish strength: 42/100
