Bitcoin mining software reveals high severity security flaw

Bitcoin Core developers flagged a "high severity" software flaw, CVE-2025-62861, in a November 10 report. The bug could stop affected mining nodes from preparing valid new blocks, potentially costing miners rewards; it did not directly expose Bitcoin holdings to theft. Security researcher Niklas Goegge reported it on Sept. 26, 2025; Bitcoin Core 30.0, 29.2 and 28.3 shipped the patch in October 2025, and versions 28.0-28.2 and 29.0-29.1 were affected.
