🔧 Bitcoin Core disclosed 3 vulnerabilities all at once, after keeping them under wraps for 13 months!
According to CoinDesk: Bitcoin Core published a security advisory on 11/10. The three vulnerabilities had actually been fixed in October 2025, but disclosure was delayed until now under its policy of publishing details two weeks after support for affected versions ends.
⚠️ 1) Tor allowlist vulnerability (medium severity): External Tor connections could be treated as trusted machines. “Thousands of mainnet nodes” were affected, bypassing anti-spam and privacy restrictions.
⚠️ 2) High severity: A rule introduced in version 28.0 could prevent mining nodes from generating valid block templates during a chain reorganization. Restarting was required to restore functionality.
⚠️ 3) Medium severity: A malicious connection could cause a node to stall while processing new blocks for 10 minutes. Repeated attacks could prolong the disruption.
✅ The advisory reported no real-world attacks. Patches were released long ago, so simply upgrade to the latest version. Nodes without the allowlist enabled are unaffected.
📌 My take: This is neutral news for the price, but a reminder that BTC’s security depends on continuous patching. Starting in October, core developers changed the rules: bugs that can be found with a single AI prompt will be fixed and disclosed more quickly.
BTC is currently around 73,000, ETFs have seen outflows for four consecutive days, and the Fear & Greed Index is at 28. Which do you think has more impact on your positioning: bearish fundamentals or technical news like this? Let’s talk in the comments 👇
