When the \"Save to File\" feature is enabled, filenames taken from HTTP response Content-Disposition headers are joined to the temporary directory path without sanitization. An attacker controlling an external HTTP server can supply filenames containing ../ sequences, allowing arbitrary file writes to locations the Langflow process can access.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-8859","publishedAt":"2026-07-17T20:17:31.643Z","cveId":"CVE-2026-8859","cweIds":["CWE-22"],"cvssScore":"9.9","cvssSeverity":"critical","severity":"critical","attackType":["other"],"issueType":"vulnerability","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":[],"affectedVendorsRaw":["IBM Langflow OSS"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":"IBM Langflow OSS path traversal in APIRequest Save to File feature","headlinePromptVersion":"h1","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","attackVector":"network","attackComplexity":"low","privilegesRequired":"low","userInteraction":"none","exploitMaturity":"unknown","epssScore":0.0056,"epssCheckedAt":"2026-11-12T18:09:37.786Z","kevDateAdded":null,"advisoryAliases":["GHSA-mvq6-wcf9-wpxf"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":"2026-11-09T18:09:59.169Z","patchAvailable":null,"disclosureDate":"2026-07-17T20:17:31.643Z","fixReleasedAt":null,"daysToFix":null,"fixCheckedAt":null,"capecIds":["CAPEC-126"],"crossRefCount":0,"attackSophistication":"moderate","impactType":["integrity"],"aiComponentTargeted":"framework","llmSpecific":false,"classifierConfidence":0.9,"researchCategory":null,"atlasIds":null,"fixes":[]}}
