An indirect prompt injection vulnerability in Cursor AI can be exploited in conjunction with a sandbox bypass and remote tunnel feature, potentially granting shell access to developer machines.
The key learning here is the potential for a chained attack using an indirect prompt injection combined with a sandbox bypass and Cursor's remote tunnel feature, which could grant shell access to machines. This highlights the importance of securing AI tools and components against complex, multi-step exploits that can compromise developer devices, underscoring the need for thorough threat modeling and securing communication channels in development environments.
