{"id":"CVE-2025-68949","summary":"n8n has a Webhook Node IP Whitelist Bypass via Partial String Matching","details":"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.","aliases":["GHSA-w96v-gf22-crwp"],"modified":"2026-08-12T03:51:12.657983873Z","published":"2026-01-13T18:43:20.189Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-134","CWE-284"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/68xxx/CVE-2025-68949.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/68xxx/CVE-2025-68949.json"},{"type":"ADVISORY","url":"https://github.com/n8n-io/n8n/security/advisories/GHSA-w96v-gf22-crwp"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-68949"},{"type":"REPORT","url":"https://github.com/n8n-io/n8n/issues/23399"},{"type":"FIX","url":"https://github.com/n8n-io/n8n/commit/11f8597d4ad69ea3b58941573997fdbc4de1fec5"},{"type":"FIX","url":"https://github.com/n8n-io/n8n/pull/23399"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/n8n-io/n8n","events":[{"introduced":"15fb6cbd4a75d38cadb3962f9c0194d81fc3fd35"},{"fixed":"67e25c890a7817b36190f7b679fb102864fe02c2"},{"fixed":"11f8597d4ad69ea3b58941573997fdbc4de1fec5"}],"database_specific":{"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:n8n:n8n:*:*:*:*:*:node.js:*:*","extracted_events":[{"introduced":"1.36.0"},{"fixed":"2.2.0"}]}}],"versions":["n8n@1.115.0","n8n@1.113.0","n8n@1.107.0","n8n@1.105.0","n8n@1.103.0","n8n@1.94.0","n8n@1.93.0","n8n@1.92.0","n8n@1.89.0","n8n@1.74.0","n8n@1.73.0","n8n@1.71.0","n8n@1.69.0","n8n@1.64.0","n8n@1.63.0","n8n@1.62.1","n8n@1.60.0","n8n@1.59.0","n8n@1.58.0","n8n@1.56.0","n8n@1.55.0","n8n@1.51.0","n8n@1.50.0","n8n@1.49.0","n8n@1.47.0","n8n@1.42.0","n8n@1.40.0","n8n@1.37.0","n8n@1.36.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-68949.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"}]}
