The operation substitutes evaluated {{ ... }} expression values directly into the raw SQL string without parameterization. When a workflow uses this operation with expression-sourced values and is connected to an externally-reachable trigger (such as a Webhook node), attacker-controlled input reaching those expressions results in SQL injection, allowing execution of arbitrary SQL with the configured MySQL credentials' privileges. The MySQL v2 node, which uses parameterized queries, is not affected.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:N/SC:H/SI:H/SA:N","score":5.3,"severity":null}],"references":["https://github.com/n8n-io/n8n/security/advisories/GHSA-hwmj-qg4v-cvg9","https://www.vulncheck.com/advisories/n8n-sql-injection-in-mysql-v1-executequery-operation-via-expression-interpolation"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-42269","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Jul 8, 2026, 1:49:13 PM","dateUpdated":"Jul 9, 2026, 1:39:51 PM"},"relatedAdvisories":[{"id":"NCSC-2026-0228","title":"Kwetsbaarheden verholpen in n8n workflow automation platform","vulnerabilityIds":["CVE-2026-59253","CVE-2026-59257","CVE-2026-59206","CVE-2026-59207","CVE-2026-59208","CVE-2026-59209"]}],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
