The method sanitized package name arguments with an incomplete blocklist before building a 'pip install' command in the Code Interpreter sandbox, letting crafted arguments bypass validation. The most serious bypasses were the '--index-url' flag, which could redirect package resolution to a third-party-controlled PyPI server, and the '-r' flag, which could read and expose arbitrary sandbox files.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://aws.amazon.com/security/security-bulletins/rss/2026-044-aws/","publishedAt":"2026-06-17T21:16:00.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"high","attackType":["supply_chain","other"],"issueType":"vulnerability","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":["Amazon"],"affectedVendorsRaw":["AWS Bedrock AgentCore","bedrock-agentcore Python SDK"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":null,"headlinePromptVersion":null,"cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":null,"epssScore":null,"epssCheckedAt":null,"kevDateAdded":null,"advisoryAliases":null,"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":null,"disclosureDate":"2026-06-17T21:16:00.000Z","fixReleasedAt":null,"daysToFix":null,"fixCheckedAt":null,"capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality","integrity"],"aiComponentTargeted":"agent","llmSpecific":false,"classifierConfidence":0.93,"researchCategory":null,"atlasIds":["AML.T0010"],"fixes":[]}}
