Sandbox escape – Definition & Meaning

Definition of sandbox escape

: an event in which code or an AI agent gets beyond the technical restrictions of its isolated execution environment and reaches files, networks, credentials, or systems that the environment was meant to block
- The evaluation was halted after a sandbox escape gave the agent access to the public internet.
- Scoped credentials limited the damage even though the attacker achieved a sandbox escape.
- Researchers used frontier agents to search for sandbox escapes before resuming high-risk training.

Origin & history

Sandbox escape is an established computer-security term. It became prominent in AI-agent safety in 2026 after incidents and benchmarks showed that tool-using agents could exploit software flaws or weak boundaries to reach systems outside their evaluation environments.
