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":"2025-12-04T21:16:09.393+00:00","modifiedAt":"2026-10-18T15:10:00.097+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · security-advisories@github.com · Secondary","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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":1.8,"severity":"LOW"}],"references":["https://github.com/anthropic-experimental/sandbox-runtime/commit/bea2930cc1db9c73a1b15acf6dc19c5261aec1f3","https://github.com/anthropic-experimental/sandbox-runtime/security/advisories/GHSA-9gqj-5w7c-vx47"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2025-66479","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-693"],"productCriteria":[],"sourceDates":{"published":"2025-12-04T21:16:09.393","lastModified":"2026-10-18T15:10:00.097"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
