🧅 Your Tor node was "trusted" by strangers. For 13 months. Nobody told you.

Bitcoin Core just disclosed CVE-2025-62860: if a node's non-default -whitelist range covered its Tor daemon, every inbound Tor peer inherited trusted rights.

✅ No coin theft
✅ No reported exploits
✅ Fixed in Oct 2025 (30.0 / 29.2 / 28.3)

The real question: should critical bugs wait 13 months to be disclosed?

#BitcoinCoreDisclosesTorTrafficVulnerability 🧅⚠️

Bitcoin was NOT hacked.
But this disclosure is BIG. Read it.

Bitcoin Core just disclosed 3 vulnerabilities - including a Tor bug that affected *thousands of nodes.

What happened?

Bitcoin Core has a setting called `-whitelist`.
It gives TRUSTED connections extra permissions - like bypassing spam limits and privacy protections.

The bug:
Tor connections look like they come from your local Tor software.
If that local Tor IP was inside the whitelist range, then *EVERY stranger connecting via Tor was treated as TRUSTED.*

Result: Thousands of reachable mainnet nodes were whitelisting ALL incoming Tor connections.

The Facts You Need:

CVE:* CVE-2025-62860
Severity:* Medium
Coins stolen?* NO ❌
Wallets hacked?* NO ❌
Active exploit found?* NO ❌
Nodes without whitelist?* NOT AFFECTED ✅

*Was it already fixed?*
YES.
Fixed in *October 2025* - in v30.0, v29.2, v28.3
Disclosure came on *Nov 10, 2026* - because Core only publishes details AFTER the last affected version reaches end-of-life. That's their security policy.

*2 Other Bugs Disclosed:*
1. *HIGH severity* - Mining node could fail to build valid block templates after a reorg until restart
2. *MEDIUM severity* - Attacker could stall block processing for 10 minutes

*What should you do?
If you run a node, make sure you are on the LATEST version. Update = Safe.

This is not FUD. This is TRANSPARENCY.
This is exactly why Bitcoin is still the most trusted network in crypto. 💪

Question:
Is this late disclosure GOOD security or TOO LATE?

🚨 BITCOIN CORE DISCLOSES 3 VULNERABILITIES: IS THE NETWORK SAFE? 🚨

​Bitcoin Core just released details on three security bugs, including a notable Tor traffic flaw. If you are a trader or node operator, here is the verified breakdown of what actually happened and how it impacts the market:

​⚠️ The Tor Vulnerability (CVE-2025-62860):

Thousands of reachable mainnet nodes running non-default -whitelist configurations accidentally gave inbound Tor connections trusted permissions. This bypassed vital DoS and privacy protections, leaving nodes exposed.

​🛑 The Mining Flaw (CVE-2025-62861):

A high-severity bug caused mempool inconsistencies during chain reorganizations. This could halt block template creation for affected miners, requiring a forced restart to fix.

​🛡️ The Bottom Line (Trader Impact = ZERO):

Don't panic. There are zero active exploits and no user funds were ever at risk. Developers quietly patched these bugs back in October 2025 with the v30.0 and v29.2 updates. This delayed disclosure on November 10, 2026, is simply standard security protocol now that older vulnerable versions have reached end-of-life.

​Decentralized money requires well-maintained software. Update your nodes!

🚨 Bitcoin Core just revealed 3 security flaws — one could stop affected mining nodes from producing blocks

The surprising part?
All three were FIXED over a year ago
On November 10, Bitcoin Core publicly disclosed three vulnerabilities after the last affected release series reached end of life
Here's what the bugs could do 👇

$BTC

🔴 HIGH severity — A chain reorganization could corrupt an affected node's mempool, preventing miners from creating valid block templates until restarting
🟠 MEDIUM severity — Incoming Tor connections could mistakenly receive trusted-peer privileges on nodes with certain whitelist settings
🟠 MEDIUM severity — A malicious peer could repeatedly delay block processing under specific conditions
But this is NOT evidence that Bitcoin's consensus rules were broken or BTC was stolen
The fixes arrived in October 2025


⚠️ For node operators, the important question is whether you're still running vulnerable software
Bitcoin Core 29.2 and 30.0 already included all three fixes — use a currently supported release
The vulnerability disclosure is new
The protection isn't

🛠️ Bitcoin Core discloses three patched security flaws, including a high-severity mining bug

Bitcoin Core has publicly disclosed three vulnerabilities, all of which were already fixed in releases shipped in October 2025.

The high-severity bug (CVE-2025-62861) hit versions 28.0-28.2 and 29.0-29.1: after a chain reorganization it could leave the mempool inconsistent, and affected miners had to restart their nodes before they could build valid block templates again.

Two medium-severity flaws let a malicious peer delay block processing by up to 10 minutes via compact blocks, and gave whitelist permissions to incoming Tor peers on some configurations. Bitcoin Core said "thousands" of reachable mainnet nodes had been whitelisting incoming Tor connections.

⭐ No funds were at risk and the fixes are out, but node operators and miners on older versions should make sure they run Bitcoin Core 30.0 or 29.2+, a reminder of how much network reliability depends on keeping infrastructure updated.

A tech explainer: What exactly is this “Tor vulnerability”? Explained in one sentence

$BTC A lot of people panicked when they saw “Bitcoin Core discloses Tor vulnerability.” Don’t rush to judgment—first get the timeline straight.

Vulnerability ID: CVE-2025-62860. The core issue in one sentence: when service providers bundle Bitcoin Core with Tor, incoming Tor traffic is mistakenly classified as “local traffic.” If you have -whitelist enabled and the IP range includes your local Tor proxy, strangers connecting from outside via Tor inherit the permissions you grant to “trusted local nodes,” while spam protections and privacy restrictions are relaxed.

Key facts:

· Fixed versions: 30.0 / 29.2 / 28.3, released back in October 2025
· Public disclosure: November 10, 2026, two weeks after the last affected 29.x series reached end of life
· Nodes that did not enable -whitelist were never affected

This isn’t a “brand-new vulnerability that just appeared today.” It’s a routine disclosure more than a year after the patch was released. Public disclosure ≠ new risk—don’t let the headlines sway you.
#BitcoinCore #安全

#BitcoinCoreDisclosesTorTrafficVulnerability Don’t panic over the Tor bug news. The real story is “delay,” not “danger.” 🧅
Bitcoin Core disclosed 3 patched vulnerabilities. “Thousands” of reachable mainnet nodes were whitelisting incoming Tor connections, which removed some DoS limits and privacy protections. Nodes that didn’t have this non-default setting were not affected. (theblock)
The truth about the timeline:
✅ The fix was included in Bitcoin Core 30.0 (Oct 10, 2025) and 29.2 (Oct 14, 2025). The last vulnerable version reached end-of-life on Oct 27, 2026.
✅ The project ships the fix first, then shares the vulnerability details later.
⚠️ This is not an issue with consensus rules. The risk was to node privacy and reliability, not to coins or the Bitcoin protocol. (theblock) (cryptovalleyjournal)
My analysis: This is a textbook example of “responsible disclosure.” First the patch, then time for users to upgrade, and only then a public advisory. That’s the power of open source: a bug is found, fixed, and later everything is made public. But there’s a lesson here too: operators running old node versions should upgrade now.

🚨 BREAKING NEWS: THE SOFTWARE THAT RUNS THE BITCOIN NETWORK JUST ADMITTED IT HAS 3 VULNERABILITIES!

Bitcoin Core, the software that runs most Bitcoin nodes, publicly disclosed 3 security vulnerabilities on November 10. The most serious bug could prevent miners’ nodes from creating a new block after a chain reorganization, until they are restarted.

The good news: all 3 bugs were patched in October 2025, no exploits have been reported, and not a single BTC was lost.

But here’s the chilling part: nearly 9% of nodes on the network—about 1,885 nodes—are STILL running an outdated, vulnerable version.

Meanwhile, BTC is hovering around $73,000, ETH is languishing around $2,050, and the Fear & Greed Index is down to 28. The market is fearful, but the Bitcoin network keeps running.

Save this—hardly anyone is paying attention to this news, but it’s extremely important. Follow me; I post it here first.

🔧 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 👇

Bitcoin Core discloses 3 vulnerabilities at once: Is your node version up to date?

The bottom line: According to three disclosures published on the Bitcoin Core website on November 10, these issues affect the node’s mempool, block propagation, and connection permissions. None involves private keys or forged transactions. The fixes were released back in October 2025; only now are the details being made public.

What each of the 3 vulnerabilities does:
1. CVE-2025-62861 (high severity): During a chain reorganization, the “sibling replacement” rule for TRUC (v3) transactions can be triggered incorrectly, leaving transactions in the mempool that spend outputs that no longer exist. As a result, the node cannot generate block templates until it is restarted. Affected versions: 28.0–28.2 and 29.0–29.1. This is most damaging for miners and mining pools.
2. CVE-2025-62860 (medium severity): Nodes configured with -whitelist to allow IP ranges can also treat incoming Tor connections as whitelisted, disabling some DoS protections and privacy safeguards. The official disclosure says that because some bundled packages use this configuration by default, thousands of reachable nodes on the mainnet are affected. Nodes without -whitelist configured were never affected.
3. CVE-2025-62859 (medium severity): A malicious node can use compact blocks with tampered witness data to make a victim node get stuck waiting for the 10-minute timeout. This can be repeated indefinitely if the attacker controls all 3 of your high-bandwidth nodes, or if you have -blocksonly enabled.

The timeline is also worth noting: The earliest issue (62859) was reported on April 28, 2025, about 18 months before it was publicly disclosed. The reason is that the developers waited until the last affected release branch, 29.x, reached end of support on October 27, 2026, before publishing the details.

How to check, in two steps:
1. Run bitcoin-cli getnetworkinfo and check the subversion field. Version 30.0 and later fix all three; 29.2 fixes all three; 28.3 fixes the first two (the original disclosure for 62859 lists only 29.2 and 30.0). Version 29.x reached end of support on October 27, so the safest option is to upgrade to a release branch that is still supported.
2. If you use a bundled node package with a graphical interface, check its settings to see whether an IP range is configured under -whitelist, and confirm that the Core version included in the package is later than the versions listed above.

According to the disclosures, people who only hold coins on exchanges or in mobile wallets and do not run their own nodes do not need to take any action in response to this issue.

🚨 BITCOIN CORE REVEALS 3 SECURITY VULNERABILITIES
Node operators pay attention, Bitcoin Core has publicly disclosed 3 vulnerabilities. The most serious bug causes mining machines to fail to create new blocks, and only a restart clears it. The other two are less severe: one slows block processing by 10 minutes, and the other is related to Tor connections. All 3 issues were patched in October last year, with no known exploits so far, but about 9% of nodes are still running older versions.

Bitcoin Core has uncovered three old landmines. A high-severity vulnerability can directly freeze miners’ block production. The other two bugs can cause nodes to stall or extend trust incorrectly—truly alarming. Although this is a major cleanup of technical debt, miners face immense pressure in the short term, and the ecosystem may experience brief turbulence. Watch and wait patiently; this one really is a tough nut to crack.

Bitcoin Core quietly disclosed three vulnerabilities, and the timing is awkward.

Fixes had already shipped before the October 28 disclosure (CoinDesk). One flaw could let a connected attacker flood a node on Windows, macOS or BSD with data until it runs out of memory and crashes.

Nodes are the backbone of $BTC 's trust model, so patching matters even when price is calm. With BTC near $77,000 and the Binance hack still dominating headlines, this one got far less attention than it deserves.

Do you run your own node, and how quickly do you update after a release? Curious what the community habit really looks like.
