Prior to 3.1.0, a Server-Side Request Forgery (SSRF) protection bypass vulnerability exists in the Custom Function feature. While the application implements SSRF protection via HTTP_DENY_LIST for axios and node-fetch libraries, the built-in Node.js http, https, and net modules are allowed in the NodeVM sandbox without equivalent protection. This allows authenticated users to bypass SSRF controls and access internal network resources (e.g., cloud provider metadata services) This vulnerability is fixed in 3.1.0.","state":0,"publishedAt":"2026-04-23T20:16:15.547+00:00","modifiedAt":"2026-06-17T10:46:24.967+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:L","score":7.1,"severity":"HIGH"},{"system":"CVSS 3.1 · nvd@nist.gov · Primary","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:L","score":8.3,"severity":"HIGH"}],"references":["https://github.com/FlowiseAI/Flowise/security/advisories/GHSA-xhmj-rg95-44hv"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-41270","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Modified","weaknesses":["CWE-284","CWE-918"],"productCriteria":["cpe:2.3:a:flowiseai:flowise:*:*:*:*:*:*:*:*"],"sourceDates":{"published":"2026-04-23T20:16:15.547","lastModified":"2026-06-17T10:46:24.967"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
