The deprecated POST /api/v1/build/{flow_id}/vertices endpoint does not properly validate ownership, letting an authenticated user inject arbitrary graph data into a shared cache for any flow. The source says this may cause cross-user cache pollution, unauthorized workflow execution, or denial of service. The NVD assessment is not yet provided, and the weakness is classified as CWE-284, Improper Access Control.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-10547","publishedAt":"2026-08-05T19:17:19.847Z","cveId":"CVE-2026-10547","cweIds":["CWE-284"],"cvssScore":"5.9","cvssSeverity":"medium","severity":"medium","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 cross-user cache pollution via deprecated vertices endpoint","headlinePromptVersion":"h1","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:H/A:L","attackVector":"network","attackComplexity":"high","privilegesRequired":"low","userInteraction":"none","exploitMaturity":"unknown","epssScore":0.00405,"epssCheckedAt":"2026-11-09T18:09:51.434Z","kevDateAdded":null,"advisoryAliases":["GHSA-f7wm-r5v3-mxr4"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":"2026-11-09T12:10:56.137Z","patchAvailable":null,"disclosureDate":"2026-08-05T19:17:19.847Z","fixReleasedAt":null,"daysToFix":null,"fixCheckedAt":null,"capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["integrity","availability","confidentiality"],"aiComponentTargeted":"framework","llmSpecific":false,"classifierConfidence":0.9,"researchCategory":null,"atlasIds":null,"fixes":[]}}
