CVE-2025-66479

Name of the Vulnerable Software and Affected Versions Anthropic Sandbox Runtime versions prior to 0.0.16

Description Anthropic Sandbox Runtime is a sandboxing tool designed to enforce filesystem and network restrictions on processes. Prior to version 0.0.16, a flaw in the sandboxing logic allowed sandboxed code to potentially make network requests outside of the intended sandbox environment if the sandbox policy did not define any allowed domains. This occurred because the network sandbox was not properly enforced in such scenarios.

Recommendations Update to version 0.0.16 or later.
