Prior to version 1.99.1, an authorization vulnerability was discovered in the /rest/executions/:id/stop endpoint of n8n. An authenticated user can stop workflow executions that they do not own or that have not been shared with them, leading to potential business disruption. This issue has been patched in version 1.99.1. A workaround involves restricting access to the /rest/executions/:id/stop endpoint via reverse proxy or API gateway.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:H","score":4.9},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","score":4.3},"cwes":["CWE-862"],"references":["https://github.com/dudanogueira/n8n/commit/ca2f90c7fbaa1d661ade2f45d587d9469bc287e1","https://github.com/n8n-io/n8n/commit/e5edc60e344924230baafb11fa1f0af788e9ca9a","https://github.com/n8n-io/n8n/pull/16405","https://github.com/n8n-io/n8n/security/advisories/GHSA-gq57-v332-7666"],"products":["n8n:n8n"],"source":"nvd","synced_at":"2026-10-19T22:04:28.436527499+00:00"},"epss":{"cve":"CVE-2025-52554","score":0.00367,"percentile":0.30538,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-gq57-v332-7666","url":"https://osv.dev/vulnerability/GHSA-gq57-v332-7666","summary":"n8n is vulnerable to Improper Authorization through its `/stop` endpoint","modified":"2025-07-03T21:50:48Z","packages":[{"ecosystem":"npm","name":"n8n","purl":"pkg:npm/n8n","ranges":["<1.99.1"],"fixed":["1.99.1"]}]}],"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).
