When an LLM produces streamed output, each piece of data is recorded as a new_token event with unredacted content that bypasses the redaction process entirely, potentially leaking sensitive information to LangSmith storage.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-rr7j-v2q5-chgv","publishedAt":"2026-04-16T01:20:37.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":"medium","severity":"medium","attackType":["data_extraction"],"issueType":"vulnerability","affectedPackages":["langsmith@<= 0.7.30 (fixed: 0.7.31)","langsmith@<= 0.5.18 (fixed: 0.5.19)"],"affectedVendors":["LangChain"],"affectedVendorsRaw":["LangSmith SDK"],"classifierModel":"claude-haiku-4-5-20251001","classifierPromptVersion":"v3","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":null,"epssScore":null,"patchAvailable":true,"disclosureDate":"2026-04-16T01:20:37.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["confidentiality"],"aiComponentTargeted":"api","llmSpecific":true,"classifierConfidence":0.95,"researchCategory":null,"atlasIds":null}}
