{"id":"CVE-2026-33484","summary":"Langflow has Unauthenticated IDOR on Image Downloads","details":"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.","aliases":["GHSA-7grx-3xcx-2xv5"],"modified":"2026-04-10T05:42:47.835256Z","published":"2026-03-24T12:57:33.641Z","database_specific":{"cwe_ids":["CWE-284","CWE-639","CWE-862"],"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33484.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33484.json"},{"type":"ADVISORY","url":"https://github.com/langflow-ai/langflow/security/advisories/GHSA-7grx-3xcx-2xv5"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33484"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/langflow-ai/langflow","events":[{"introduced":"24d9e86885b877ea3e9d03cbc50b963765489721"},{"fixed":"7f3b01629629d3229550259d2a969525b2a09391"}],"database_specific":{"versions":[{"introduced":"1.0.0"},{"fixed":"1.9.0"}]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-33484.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
