Bitcoin Core developers have changed their policy on security bugs: those that language models can easily find will be fixed quickly and disclosed, instead of staying hidden for long periods. The reasoning, as explained by Antoine Poinsot, is that if an AI tool finds a bug with a single prompt, attackers can do the same. Separately, the Bitcoin Red Team programme said it reviewed 390 projects and logged 4,962 findings, 85 of them critical. Serious bugs that are hard to find will still follow a responsible disclosure process.
What it means: The decision reflects a wider shift in software security: when AI sharply cuts the cost of finding bugs, long periods of silence before disclosure lose their point. If a flaw is easy to find, delaying the announcement simply leaves users exposed while attackers may already know about it. For anyone running Bitcoin nodes, exchanges or wallet services in Greece, this means security updates will arrive more often and should be applied quickly. A process for tracking advisories and a test environment for checking new versions before production are needed. The Red Team numbers show that the ecosystem around Bitcoin, meaning wallets, libraries and services, has many more gaps than the core software itself. The same lesson applies to any software company: if your own AI tools can find vulnerabilities in your code, so can others, so it pays to use them first and regularly. For providers working under MiCA or DORA, fast vulnerability management is also a regulatory obligation rather than just good practice.
