The patch blocks dangerous command-line flags (like `-y` and `--yes`) to prevent automatic package installation, but attackers can bypass this by setting the `npm_config_yes` environment variable (a way to pass configuration to npm through the environment rather than command-line flags), which achieves the same effect. On unprotected Flowise deployments without authentication, this allows unauthenticated remote code execution (running arbitrary commands on the server).","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-xc48-889x-5qmw","publishedAt":"2026-08-04T17:09:48.000Z","cveId":"CVE-2026-69263","cweIds":null,"cvssScore":null,"cvssSeverity":"high","severity":"high","attackType":["supply_chain"],"issueType":"vulnerability","affectedPackages":["flowise-components@<= 3.1.2 (fixed: 3.1.3)","flowise@<= 3.1.2 (fixed: 3.1.3)"],"affectedVendors":["LangChain"],"affectedVendorsRaw":["Flowise"],"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":"2026-08-04T17:09:48.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["integrity","confidentiality","availability"],"aiComponentTargeted":"agent","llmSpecific":false,"classifierConfidence":0.92,"researchCategory":null,"atlasIds":["AML.T0010"]}}
