From version 1.65.0 to before 1.114.3, the use of Buffer.allocUnsafe() and Buffer.allocUnsafeSlow() in the task runner allowed untrusted code to allocate uninitialized memory. Such uninitialized buffers could contain residual data from within the same Node.js process (for example, data from prior requests, tasks, secrets, or tokens), resulting in potential information disclosure. This issue has been patched in version 1.114.3.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N","score":7.7},"cwes":["CWE-200","CWE-668"],"references":["https://github.com/n8n-io/n8n/commit/2c4c2953199733c791f739a40879ae31ca129aba","https://github.com/n8n-io/n8n/security/advisories/GHSA-49mx-fj45-q3p6"],"products":["n8n:n8n"],"source":"nvd","synced_at":"2026-10-19T22:22:27.261130201+00:00"},"epss":{"cve":"CVE-2025-61917","score":0.00399,"percentile":0.34213,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-49mx-fj45-q3p6","url":"https://osv.dev/vulnerability/GHSA-49mx-fj45-q3p6","summary":"n8n's Unsafe Buffer Allocation Allows In-Process Memory Disclosure in Task Runner","modified":"2026-02-04T20:08:42.117531Z","packages":[{"ecosystem":"npm","name":"n8n","purl":"pkg:npm/n8n","ranges":[">=1.65.0 <1.114.3"],"fixed":["1.114.3"]}]}],"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).
