In version 1.4.3 of Flowise, a reflected cross-site scripting vulnerability occurs in the `api/v1/chatflows/id` endpoint. If the default configuration is used (unauthenticated), an attacker may be able to craft a specially crafted URL that injects Javascript into the user sessions, allowing the attacker to steal information, create false popups, or even redirect the user to other websites without interaction. If the chatflow ID is not found, its value is reflected in the 404 page, which has type text/html. This allows an attacker to attach arbitrary scripts to the page, allowing an attacker to steal sensitive information. This XSS may be chained with the path injection to allow an attacker without direct 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:R/S:C/C:L/I:L/A:N","score":6.1},"cwes":["CWE-79"],"references":["https://github.com/FlowiseAI/Flowise/blob/flowise-ui%401.4.0/packages/server/src/index.ts#L312-L312","https://securitylab.github.com/advisories/GHSL-2023-232_GHSL-2023-234_Flowise/","https://github.com/FlowiseAI/Flowise/blob/flowise-ui%401.4.0/packages/server/src/index.ts#L312-L312","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-2024-36422","score":0.00406,"percentile":0.34843,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-2jch-qc96-9f5g","url":"https://osv.dev/vulnerability/GHSA-2jch-qc96-9f5g","summary":"Flowise Cross-site Scripting in api/v1/chatflows/id","modified":"2024-08-05T21:58:57.898766Z","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).
