Bitcoin Core disclosed three historical security vulnerabilities on Tuesday, including a Tor-related bypass and a high-severity mining node bug, all of which were patched in October 2025.
Bitcoin Core disclosed three security flaws on Tuesday, including one that let Tor users bypass spam and privacy protections on thousands of nodes and a high-severity bug that could stop a mining node from building valid blocks until restarted. All three were already patched in October 2025 and the advisory reports no attacks, so the network itself is unaffected going forward. The disclosures are routine and historical, arguing against any material price move for bitcoin.
Bitcoin Core developers published a formal security advisory on Tuesday detailing three vulnerabilities, including a medium-severity flaw that allowed Tor users to bypass node privacy protections. All identified bugs were patched in October 2025, with the disclosure delayed to ensure operators had sufficient time to upgrade their systems before public release.
No. The article states all three flaws were patched in releases issued in October 2025, and the advisories were only published Tuesday because of a disclosure policy that waits for operators to upgrade.
The advisory does not report any attacks. The article notes that nodes which never enabled the whitelist setting were unaffected by the Tor flaw.
