{"cve":"CVE-2025-68477","nvd":{"published":"2025-12-19T17:15:53.547","modified":"2026-10-13T11:10:00.203","status":"Analyzed","description":"Langflow is a tool for building and deploying AI-powered agents and workflows. Prior to version 1.7.0, Langflow provides an API Request component that can issue arbitrary HTTP requests within a flow. This component takes a user-supplied URL, performs only normalization and basic format checks, and then sends the request using a server-side httpx client. It does not block private IP ranges (127[.]0[.]0[.]1, the 10/172/192 ranges) or cloud metadata endpoints (169[.]254[.]169[.]254), and it returns the response body as the result. Because the flow execution endpoints (/api/v1/run, /api/v1/run/advanced) can be invoked with just an API key, if an attacker can control the API Request URL in a flow, non-blind SSRF is possible—accessing internal resources from the server’s network context. This enables requests to, and collection of responses from, internal administrative endpoints, metadata services, and internal databases/services, leading to information disclosure and providing a foothold for further attacks. Version 1.7.0 contains a patch for this issue.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":6.5},"cwes":["CWE-918"],"references":["https://github.com/langflow-ai/langflow/security/advisories/GHSA-5993-7p27-66g5","https://github.com/langflow-ai/langflow/security/advisories/GHSA-5993-7p27-66g5"],"products":["langflow:langflow"],"source":"nvd","synced_at":"2026-10-19T22:17:07.138532058+00:00"},"epss":{"cve":"CVE-2025-68477","score":0.06303,"percentile":0.93556,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-5993-7p27-66g5","url":"https://osv.dev/vulnerability/GHSA-5993-7p27-66g5","summary":"Langflow vulnerable to Server-Side Request Forgery","modified":"2026-07-07T17:56:14.632296536Z","packages":[{"ecosystem":"PyPI","name":"langflow","purl":"pkg:pypi/langflow","ranges":["<1.7.1"],"fixed":["1.7.1"]}]},{"id":"PYSEC-2026-1522","url":"https://osv.dev/vulnerability/PYSEC-2026-1522","summary":"Langflow vulnerable to Server-Side Request Forgery","modified":"2026-07-07T17:46:48.092561812Z","packages":[{"ecosystem":"PyPI","name":"langflow","purl":"pkg:pypi/langflow","ranges":["<1.7.1"],"fixed":["1.7.1"]}]}],"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).
