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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-284","CWE-639","CWE-862"],"references":["https://github.com/langflow-ai/langflow/security/advisories/GHSA-7grx-3xcx-2xv5","https://github.com/langflow-ai/langflow/security/advisories/GHSA-7grx-3xcx-2xv5"],"products":["langflow:langflow"],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-33484","score":0.0594,"percentile":0.93266,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-7grx-3xcx-2xv5","url":"https://osv.dev/vulnerability/GHSA-7grx-3xcx-2xv5","summary":"langflow has Unauthenticated IDOR on Image Downloads","modified":"2026-06-06T01:00:08.179664691Z","packages":[{"ecosystem":"PyPI","name":"langflow","purl":"pkg:pypi/langflow","ranges":[">=1.0.0 <1.9.0"],"fixed":["1.9.0"]}]},{"id":"PYSEC-2026-80","url":"https://osv.dev/vulnerability/PYSEC-2026-80","summary":"","modified":"2026-05-20T09:19:04.571976Z","packages":[{"ecosystem":"PyPI","name":"langflow","purl":"pkg:pypi/langflow","ranges":[">=1.0.0 <1.9.0"],"fixed":["1.9.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
