Under certain circumstances, a remote authenticated user can craft package name arguments that bypass input validation and execute arbitrary commands within the Code Interpreter sandbox.","solution":"Fixed in bedrock-agentcore 1.18.1. Upgrade to the latest version and patch any forked or derivative code. If upgrading is not possible, do not pass untrusted or model-generated input to install_packages(), and validate dynamic package names against strict PyPI naming rules, constraining any extras group to comma-separated identifiers, before calling the SDK.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-j6g5-3hh3-pgw8","publishedAt":"2026-07-24T22:38:56.000Z","cveId":"CVE-2026-16796","cweIds":null,"cvssScore":null,"cvssSeverity":"high","severity":"high","attackType":["other"],"issueType":"vulnerability","affectedPackages":["bedrock-agentcore@< 1.18.1 (fixed: 1.18.1)"],"affectedPackageNames":["bedrock-agentcore"],"affectedPackageRefs":["pypi:bedrock-agentcore"],"affectedVendors":[],"affectedVendorsRaw":["AWS Bedrock AgentCore","bedrock-agentcore Python SDK","Code Interpreter"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":null,"headlinePromptVersion":null,"cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0.00725,"epssCheckedAt":"2026-11-04T12:08:35.001Z","kevDateAdded":null,"advisoryAliases":["GHSA-j6g5-3hh3-pgw8"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":true,"disclosureDate":"2026-07-24T22:38:56.000Z","fixReleasedAt":"2026-07-17T19:55:19.334Z","daysToFix":-7,"fixCheckedAt":"2026-10-29T21:32:35.432Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality","integrity","availability"],"aiComponentTargeted":"framework","llmSpecific":false,"classifierConfidence":0.9,"researchCategory":null,"atlasIds":null,"fixes":[{"ecosystem":"pypi","name":"bedrock-agentcore","fixedVersion":"1.18.1","matchedVersion":"1.18.1","fixReleasedAt":"2026-07-17T19:55:19.334Z","daysToFix":-7,"match":"ecosystem","source":"tracked","status":"found","checkedAt":"2026-10-29T21:32:35.285Z"}]}}
