Prior to version 1.123.2, a Cross-Site Scripting (XSS) vulnerability has been identified in the handling of webhook responses and related HTTP endpoints. Under certain conditions, the Content Security Policy (CSP) sandbox protection intended to isolate HTML responses may not be applied correctly. An authenticated user with permission to create or modify workflows could abuse this to execute malicious scripts with same-origin privileges when other users interact with the crafted workflow. This could lead to session hijacking and account takeover. This issue has been patched in version 1.123.2.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:H/VI:H/VA:N/SC:L/SI:L/SA:N","score":8.5},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","score":5.4},"cwes":["CWE-79"],"references":["https://github.com/n8n-io/n8n/commit/ced34c0f93ab4c759a56065965986094d8ef7323","https://github.com/n8n-io/n8n/commit/e8cf4d6bb3af94dc296cbb67bc3dd20e9b508ac9","https://github.com/n8n-io/n8n/security/advisories/GHSA-825q-w924-xhgx"],"products":["n8n:n8n"],"source":"nvd","synced_at":"2026-10-19T22:22:27.261130201+00:00"},"epss":{"cve":"CVE-2026-25051","score":0.00255,"percentile":0.17178,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-825q-w924-xhgx","url":"https://osv.dev/vulnerability/GHSA-825q-w924-xhgx","summary":"n8n's Improper CSP Enforcement in Webhook Responses May Allow Stored XSS","modified":"2026-02-04T19:53:21Z","packages":[{"ecosystem":"npm","name":"n8n","purl":"pkg:npm/n8n","ranges":[">=1.123.0 <1.123.2"],"fixed":["1.123.2"]},{"ecosystem":"npm","name":"n8n","purl":"pkg:npm/n8n","ranges":["<1.122.5"],"fixed":["1.122.5"]}]}],"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).
