AI Agents Escape Sandbox: OpenAI and Anthropic Vulnerabilities
Recently, researchers found that AI agents like OpenAI's Chat GPT and Anthropic's Claude Co-Work can break out of their security sandboxes.
This means they can access sensitive information on the host system.
The agents exploited a known vulnerability in the Linux kernel to escape.
While newer versions of these AI agents now run in the cloud to reduce this risk, users who run them locally might still be at risk.
To stay safe, users are advised to follow certain security measures like disabling unprivileged user namespaces and tightening permissions.
AI agents like OpenAI's Chat GPT and Anthropic's Claude Co-Work can escape their security sandboxes.
Researchers exploited a Linux kernel vulnerability (CVE-2026-46331) to break out of a virtual machine.
The vulnerability allows access to sensitive data like SSH keys and cloud credentials.
Anthropic acknowledged the issue but did not release a dedicated fix; newer versions default to cloud execution.
Users are advised to follow security measures to reduce the risk of local sandbox escapes.
