{"data":{"id":"323bd37d-1bcf-4c54-be74-8f9c6d3180d9","title":"Anthropic Releases New Claude Sandbox, Security Guidance Plugin","summary":"Anthropic released two new security features for Claude: a self-hosted sandbox that lets Claude Managed Agents (AI systems that can perform tasks autonomously) run code in user-controlled environments like their own servers or managed providers, and a security guidance plugin for Claude Code that scans for vulnerabilities (weaknesses that attackers could exploit) as developers write code. The plugin has reduced security issues by 30-40% in internal testing by catching problems before formal code review.","solution":"Anthropic provides two explicit mitigations: (1) Deploy the Claude sandbox by configuring Claude Managed Agents to execute tools in a user-controlled environment, applying your own network policies, audit logging, and security tooling while keeping files and repositories within your perimeter; (2) Use the security guidance plugin for Claude Code, available through the official Anthropic marketplace, which scans for vulnerabilities during file edits, after AI-generated changes, and at commit time to catch issues before full code review.","labels":["security","safety"],"sourceUrl":"https://www.securityweek.com/anthropic-releases-new-claude-sandbox-security-guidance-plugin/","publishedAt":"2026-05-27T06:43:08.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":[],"issueType":"news","affectedPackages":null,"affectedVendors":["Anthropic"],"affectedVendorsRaw":["Anthropic","Claude","Claude Code","Claude Managed Agents","Cloudflare","Daytona","Modal","Vercel"],"classifierModel":"claude-haiku-4-5-20251001","classifierPromptVersion":"v3","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":null,"epssScore":null,"patchAvailable":null,"disclosureDate":"2026-05-27T06:43:08.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["integrity","availability"],"aiComponentTargeted":"agent","llmSpecific":true,"classifierConfidence":0.85,"researchCategory":null,"atlasIds":null}}
