In version 1.4.3 of Flowise, A CORS misconfiguration sets the Access-Control-Allow-Origin header to all, allowing arbitrary origins to connect to the website. In the default configuration (unauthenticated), arbitrary origins may be able to make requests to Flowise, stealing information from the user. This CORS misconfiguration may be chained with the path injection to allow an attacker attackers without access to Flowise to read arbitrary files from the Flowise server. As of time of publication, no known patches are available.","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-346"],"references":["https://github.com/FlowiseAI/Flowise/blob/e93ce07851cdc0fcde12374f301b8070f2043687/packages/server/src/index.ts#L122","https://securitylab.github.com/advisories/GHSL-2023-232_GHSL-2023-234_Flowise/","https://github.com/FlowiseAI/Flowise/blob/e93ce07851cdc0fcde12374f301b8070f2043687/packages/server/src/index.ts#L122","https://securitylab.github.com/advisories/GHSL-2023-232_GHSL-2023-234_Flowise/"],"products":["flowiseai:flowise"],"source":"nvd","synced_at":"2026-10-19T21:52:00.836172422+00:00"},"epss":{"cve":"CVE-2024-36421","score":0.08495,"percentile":0.95036,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-66f2-xxgm-f6xp","url":"https://osv.dev/vulnerability/GHSA-66f2-xxgm-f6xp","summary":"Flowise Cors Misconfiguration in packages/server/src/index.ts","modified":"2024-08-05T22:11:57.886781Z","packages":[{"ecosystem":"npm","name":"flowise","purl":"pkg:npm/flowise","ranges":["<=1.4.3"],"fixed":[]}]}],"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).
