This could allow unauthorized access to sensitive operations like file access or database queries depending on which tools are enabled.","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":["prompt_injection"],"issueType":"vulnerability","affectedPackages":["langroid@<= 0.65.2 (fixed: 0.65.3)"],"affectedVendors":["LangChain"],"affectedVendorsRaw":["Langroid"],"classifierModel":"claude-haiku-4-5-20251001","classifierPromptVersion":"v3","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0,"patchAvailable":true,"disclosureDate":"2026-07-06T20:42:18.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["integrity","confidentiality"],"aiComponentTargeted":"agent","llmSpecific":false,"classifierConfidence":0.95,"researchCategory":null,"atlasIds":["AML.T0051"]}}
