Details of the vulnerabilities

They will only be published once the majority of nodes have been updated, so as not to make an attack easier in the meantime.

Through an AI-assisted code audit, via OpenAI's Daybreak cyberdefence programme, which lifts the usual restrictions on vulnerability research.
