The tool dispatch path in agent_response() → handle_message() → get_tool_messages() does not check whether the message came from Entity.USER or Entity.LLM. Depending on which handled tools are enabled, impact can include file read/write, database query execution, or access to internal orchestration tools.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-gjgq-w2m6-wr5q","publishedAt":"2026-07-06T20:42:18.000Z","cveId":"CVE-2026-54771","cweIds":null,"cvssScore":null,"cvssSeverity":"high","severity":"high","attackType":["other"],"issueType":"vulnerability","affectedPackages":["langroid@<= 0.65.2 (fixed: 0.65.3)"],"affectedPackageNames":["langroid"],"affectedPackageRefs":["pypi:langroid"],"affectedVendors":[],"affectedVendorsRaw":["Langroid"],"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":0.00392,"epssCheckedAt":"2026-10-15T00:11:27.969Z","kevDateAdded":null,"advisoryAliases":["GHSA-gjgq-w2m6-wr5q"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":true,"disclosureDate":"2026-07-06T20:42:18.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["confidentiality","integrity"],"aiComponentTargeted":"agent","llmSpecific":false,"classifierConfidence":0.9,"researchCategory":null,"atlasIds":null}}
