Bitcoin Core updates security policy due to ease of vulnerability discovery by AI

Bitcoin Core is changing its security vulnerability policy because large language models have made certain software flaws significantly easier to discover. Under the updated policy, vulnerabilities deemed "easily discoverable," such as those found through a simple LLM prompt, will receive fixes as soon as possible across all maintained major versions, with security advisories published alongside the updates. Other vulnerabilities will follow severity-based disclosure schedules, while critical bugs will require an ad-hoc procedure. Antoine Poinsot, a Bitcoin Core developer, announced this change in an email to the Bitcoin Development Mailing List on Thursday.
