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."},{"lang":"es","value":"Anthropic Sandbox Runtime es una herramienta de sandboxing ligera para aplicar restricciones de sistema de archivos y de red a procesos arbitrarios a nivel del sistema operativo, sin requerir un contenedor. Versiones anteriores a 0.0.16, debido a un error en la lógica de sandboxing, sandbox-runtime no aplicaba correctamente un sandbox de red si la política del sandbox no configuraba ningún dominio permitido. Esto podría permitir que el código en el sandbox realizara solicitudes de red fuera del sandbox. Un parche para esto fue lanzado en la v0.0.16."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"anthropic-experimental","product":"sandbox-runtime","versions":[{"version":"< 0.0.16","status":"affected"}]}]}],"metrics":{"cvssMetricV40":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"4.0","vectorString":"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","baseScore":1.8,"baseSeverity":"LOW","attackVector":"LOCAL","attackComplexity":"LOW","attackRequirements":"PRESENT","privilegesRequired":"HIGH","userInteraction":"NONE","vulnConfidentialityImpact":"LOW","vulnIntegrityImpact":"NONE","vulnAvailabilityImpact":"NONE","subConfidentialityImpact":"NONE","subIntegrityImpact":"NONE","subAvailabilityImpact":"NONE","exploitMaturity":"NOT_DEFINED","confidentialityRequirement":"NOT_DEFINED","integrityRequirement":"NOT_DEFINED","availabilityRequirement":"NOT_DEFINED","modifiedAttackVector":"NOT_DEFINED","modifiedAttackComplexity":"NOT_DEFINED","modifiedAttackRequirements":"NOT_DEFINED","modifiedPrivilegesRequired":"NOT_DEFINED","modifiedUserInteraction":"NOT_DEFINED","modifiedVulnConfidentialityImpact":"NOT_DEFINED","modifiedVulnIntegrityImpact":"NOT_DEFINED","modifiedVulnAvailabilityImpact":"NOT_DEFINED","modifiedSubConfidentialityImpact":"NOT_DEFINED","modifiedSubIntegrityImpact":"NOT_DEFINED","modifiedSubAvailabilityImpact":"NOT_DEFINED","Safety":"NOT_DEFINED","Automatable":"NOT_DEFINED","Recovery":"NOT_DEFINED","valueDensity":"NOT_DEFINED","vulnerabilityResponseEffort":"NOT_DEFINED","providerUrgency":"NOT_DEFINED"}}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2025-12-05T17:04:23.072749Z","id":"CVE-2025-66479","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-693"}]}],"references":[{"url":"https://github.com/anthropic-experimental/sandbox-runtime/commit/bea2930cc1db9c73a1b15acf6dc19c5261aec1f3","source":"security-advisories@github.com"},{"url":"https://github.com/anthropic-experimental/sandbox-runtime/security/advisories/GHSA-9gqj-5w7c-vx47","source":"security-advisories@github.com"}]}
