[Vercel: Unauthorized Access to Some Systems Due to Context.ai Breach] According to Vercel, some internal systems were accessed without authorization due to a breach of the third-party AI tool Context.ai used by employees. A small number of customer environment variables not marked as 'sensitive' may have been exposed. There is no evidence indicating that sensitive data or the supply chain was tampered with, and platform services are operating normally. Vercel has partnered with Mandiant to investigate and has reported the incident to law enforcement. Users are advised to enable multi-factor authentication, rotate credentials, and review account activity logs.
