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":"2026-07-20T12:04:51.673+00:00","modifiedAt":"2026-10-08T15:23:51.846+00:00","affected":[{"ecosystem":"Vendor product","name":"surrealdb","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"surrealdb\",\n                    \"product\": \"surrealdb\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"packageURL\": \"pkg:cargo/surrealdb\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"2.6.1\"\n                        },\n                        {\n                            \"version\": \"2.6.1\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"surrealdb","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"surrealdb\",\n                    \"product\": \"surrealdb\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"packageURL\": \"pkg:cargo/surrealdb\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"3.0.0-beta.3\"\n                        },\n                        {\n                            \"version\": \"3.0.0-beta.3\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"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":"MEDIUM"}],"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://www.cve.org/CVERecord?id=CVE-2026-63762","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-63762","identifiers":["CVE-2026-63762"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
