{"id":"CVE-2026-33484","state":"PUBLISHED","title":"Langflow has Unauthenticated IDOR on Image Downloads","description":"Langflow is a tool for building and deploying AI-powered agents and workflows. In versions 1.0.0 through 1.8.1, the `/api/v1/files/images/{flow_id}/{file_name}` endpoint serves image files without any authentication or ownership check. Any unauthenticated request with a known flow_id and file_name returns the image with HTTP 200. In a multi-tenant deployment, any attacker who can discover or guess a `flow_id` (UUIDs can be leaked through other API responses) can download any user's uploaded images without credentials. Version 1.9.0 contains a patch.","publishedAt":"2026-03-24T12:57:33.641Z","updatedAt":"2026-03-24T13:37:14.286Z","severity":{"score":7.5,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["langflow-ai langflow"],"affected":[{"vendor":"langflow-ai","product":"langflow","versions":[{"version":">= 1.0.0, < 1.9.0","status":"affected"}]}],"references":["https://github.com/langflow-ai/langflow/security/advisories/GHSA-7grx-3xcx-2xv5"],"weaknesses":["CWE-284","CWE-639","CWE-862"],"ingestedAt":"2026-10-29T20:11:40.391Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/33xxx/CVE-2026-33484.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-33484","state":"PUBLISHED","datePublished":"2026-03-24T12:57:33.641Z","dateUpdated":"2026-03-24T13:37:14.286Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-03-20T16:16:48.970Z"},"containers":{"cna":{"title":"Langflow has Unauthenticated IDOR on Image Downloads","descriptions":[{"lang":"en","value":"Langflow is a tool for building and deploying AI-powered agents and workflows.
