Prior to 0.0.16, due to a bug in sandboxing logic, sandbox-runtime did not properly enforce a network sandbox if the sandbox policy did not configure any allowed domains. This could allow sandboxed code to make network requests outside of the sandbox. A patch for this was released in v0.0.16.","state":0,"publishedAt":"2025-12-04T20:57:20.631+00:00","modifiedAt":"2025-12-05T17:04:34.471+00:00","affected":[{"ecosystem":"Vendor product","name":"sandbox-runtime","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"anthropic-experimental\",\n                    \"product\": \"sandbox-runtime\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 0.0.16\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:H/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","score":1.8,"severity":"LOW"}],"references":["https://github.com/anthropic-experimental/sandbox-runtime/security/advisories/GHSA-9gqj-5w7c-vx47","https://github.com/anthropic-experimental/sandbox-runtime/commit/bea2930cc1db9c73a1b15acf6dc19c5261aec1f3"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2025-66479","license":"CVE Program Terms of Use","key":"cve-program:CVE-2025-66479","identifiers":["CVE-2025-66479"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
