The security check that validates webhook URLs can be bypassed because MLflow follows HTTP redirects without re-validating the redirect target, allowing an attacker to redirect from an allowed public server to internal/private addresses like metadata services.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-7gwp-5pfp-969j","publishedAt":"2026-08-17T21:58:51.000Z","cveId":"CVE-2026-64849","cweIds":null,"cvssScore":null,"cvssSeverity":"critical","severity":"critical","attackType":["supply_chain"],"issueType":"vulnerability","affectedPackages":["mlflow@< 3.15.0 (fixed: 3.15.0)"],"affectedVendors":["HuggingFace"],"affectedVendorsRaw":["MLflow"],"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":"2026-08-17T21:58:51.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality","integrity"],"aiComponentTargeted":"inference","llmSpecific":false,"classifierConfidence":0.92,"researchCategory":null,"atlasIds":["AML.T0010"]}}
