{"cve":"CVE-2025-68949","nvd":{"published":"2026-01-13T19:16:15.637","modified":"2026-06-17T09:59:52.797","status":"Analyzed","description":"n8n is an open source workflow automation platform. From 1.36.0 to before 2.2.0, the Webhook node’s IP whitelist validation performed partial string matching instead of exact IP comparison. As a result, an incoming request could be accepted if the source IP address merely contained the configured whitelist entry as a substring. This issue affected instances where workflow editors relied on IP-based access controls to restrict webhook access. Both IPv4 and IPv6 addresses were impacted. An attacker with a non-whitelisted IP could bypass restrictions if their IP shared a partial prefix with a trusted address, undermining the intended security boundary. This vulnerability is fixed in 2.2.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3},"cwes":["CWE-134","CWE-284"],"references":["https://github.com/n8n-io/n8n/commit/11f8597d4ad69ea3b58941573997fdbc4de1fec5","https://github.com/n8n-io/n8n/issues/23399","https://github.com/n8n-io/n8n/pull/23399","https://github.com/n8n-io/n8n/security/advisories/GHSA-w96v-gf22-crwp"],"products":["n8n:n8n"],"source":"nvd","synced_at":"2026-10-19T22:19:41.481987139+00:00"},"epss":{"cve":"CVE-2025-68949","score":0.003,"percentile":0.22776,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-w96v-gf22-crwp","url":"https://osv.dev/vulnerability/GHSA-w96v-gf22-crwp","summary":"n8n: Webhook Node IP Whitelist Bypass via Partial String Matching","modified":"2026-02-03T02:59:51.944343Z","packages":[{"ecosystem":"npm","name":"n8n","purl":"pkg:npm/n8n","ranges":[">=1.36.0 <2.2.0"],"fixed":["2.2.0"]}]}],"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).
