Any user able to execute arbitrary queries — including unauthenticated guests when --allow-guests is enabled — can use built-in string functions to construct a large string and pass it to the JavaScript runtime for compilation, triggering a null pointer dereference in the underlying QuickJS-NG engine. This causes the server process to terminate immediately without graceful shutdown, requiring a manual restart. The issue was fixed by updating the rquickjs dependency from v0.9.0 to v0.11.0.","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:H/SC:N/SI:N/SA:N","score":6,"severity":null}],"references":["https://github.com/surrealdb/surrealdb/security/advisories/GHSA-xx7m-69ff-9crp","https://www.vulncheck.com/advisories/surrealdb-before-denial-of-service-via-scripting"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-45933","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Jul 20, 2026, 12:04:51 PM","dateUpdated":"Oct 8, 2026, 3:23:51 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
