An authenticated remote attacker can send a spoofed X-Forwarded-For: 127.0.0.1 header, making the server treat the request as local and bypass the \"local-only\" restriction. This lets the attacker write or overwrite an MCP client configuration file on the server's filesystem.","solution":"Fixed in 1.10.3.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-105741","publishedAt":"2026-10-05T21:16:35.740Z","cveId":"CVE-2026-105741","cweIds":["CWE-290","CWE-345"],"cvssScore":"7.1","cvssSeverity":"high","severity":"high","attackType":["other"],"issueType":"vulnerability","affectedPackages":["langflow@>= 1.5.0, < 1.10.3 (fixed: 1.10.3)"],"affectedPackageNames":["langflow"],"affectedVendors":[],"affectedVendorsRaw":["Langflow"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":"Langflow IP spoofing bypasses local-only restriction on MCP install endpoint","headlinePromptVersion":"h1","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:L","attackVector":"network","attackComplexity":"low","privilegesRequired":"low","userInteraction":"none","exploitMaturity":"unknown","epssScore":0.00212,"epssCheckedAt":"2026-10-10T06:42:01.794Z","kevDateAdded":null,"advisoryAliases":["GHSA-4f6c-2vvp-gw82"],"affectedPackagesSource":"ghsa","affectedPackagesCheckedAt":"2026-10-10T03:42:56.595Z","patchAvailable":true,"disclosureDate":"2026-10-05T21:16:35.740Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["integrity"],"aiComponentTargeted":"framework","llmSpecific":false,"classifierConfidence":0.9,"researchCategory":null,"atlasIds":["AML.T0010"]}}
