Bitcoin Core speeds up security fixes for AI-found bugs

Bitcoin Core cuts wait times for easy-to-find bugs

Bitcoin Core has changed its security rules to release fixes faster for vulnerabilities that AI tools can discover with little effort. The project previously kept such bugs under long embargoes, but the new policy prioritizes speed to ensure users get patched software before the details become public.

Developers approved this change on Thursday, as announced by Antoine Poinsot, a developer at Chaincode Labs. He noted that large language models have made it much easier to find specific types of software flaws, which has increased the number of reports received by the project.

How the new disclosure process works

• During the review process, maintainers can flag a bug as “easily discoverable.”
• This label applies to issues that can be found with minimal effort, such as through a simple prompt to an AI tool.
• For these specific bugs, the team will send a fix to every maintained version of the software as quickly as possible.
• A security advisory containing basic details will be published at the same time the fixed software is released.

Reactions to AI-driven security pressure

This policy shift follows several months of high-pressure security events involving AI. In late July, a group of 16 volunteers called the Bitcoin Red Team used AI models to scan 390 open-source repositories and logged nearly 5,000 findings. Shortly after, a security flaw in a popular merchant payment tool was exploited, causing financial losses.

Antoine Riard, another developer, suggested keeping some details private to avoid panic, but Poinsot rejected this idea. He argued that alerting users without providing a specific fix could cause unnecessary risk by making people rush to upgrade or disconnect.

Confirmed policy changes and limitations

The confirmed facts are that the project now separates “easily discoverable” bugs from others. The long embargo periods that once lasted up to a year for high-severity issues no longer apply to this new category. However, critical bugs that could allow theft of coins or cause a permanent split in the Bitcoin network are still handled case-by-case and remain outside this fast-track policy.

Why this matters for Bitcoin users

Because AI tools can now find these bugs so quickly, keeping the information secret for a long time does not protect users. Instead, it delays the release of the patch. The new approach ensures that fixed software is available sooner, even if it has less testing time before release. This reduces the window where an attacker could exploit the flaw after it becomes public knowledge.
