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":"2026-07-20T12:19:46.477+00:00","modifiedAt":"2026-07-22T19:41:01.317+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · disclosure@vulncheck.com · Secondary","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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":6,"severity":"MEDIUM"},{"system":"CVSS 3.1 · nvd@nist.gov · Primary","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":6.5,"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://nvd.nist.gov/vuln/detail/CVE-2026-63762","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-476"],"productCriteria":["cpe:2.3:a:surrealdb:surrealdb:*:*:*:*:*:*:*:*","cpe:2.3:a:surrealdb:surrealdb:3.0.0:alpha1:*:*:*:*:*:*","cpe:2.3:a:surrealdb:surrealdb:3.0.0:alpha10:*:*:*:*:*:*","cpe:2.3:a:surrealdb:surrealdb:3.0.0:alpha11:*:*:*:*:*:*","cpe:2.3:a:surrealdb:surrealdb:3.0.0:alpha12:*:*:*:*:*:*","cpe:2.3:a:surrealdb:surrealdb:3.0.0:alpha13:*:*:*:*:*:*","cpe:2.3:a:surrealdb:surrealdb:3.0.0:alpha14:*:*:*:*:*:*","cpe:2.3:a:surrealdb:surrealdb:3.0.0:alpha16:*:*:*:*:*:*","cpe:2.3:a:surrealdb:surrealdb:3.0.0:alpha17:*:*:*:*:*:*","cpe:2.3:a:surrealdb:surrealdb:3.0.0:alpha18:*:*:*:*:*:*","cpe:2.3:a:surrealdb:surrealdb:3.0.0:alpha2:*:*:*:*:*:*","cpe:2.3:a:surrealdb:surrealdb:3.0.0:alpha3:*:*:*:*:*:*","cpe:2.3:a:surrealdb:surrealdb:3.0.0:alpha4:*:*:*:*:*:*","cpe:2.3:a:surrealdb:surrealdb:3.0.0:alpha5:*:*:*:*:*:*","cpe:2.3:a:surrealdb:surrealdb:3.0.0:alpha6:*:*:*:*:*:*","cpe:2.3:a:surrealdb:surrealdb:3.0.0:alpha7:*:*:*:*:*:*","cpe:2.3:a:surrealdb:surrealdb:3.0.0:alpha8:*:*:*:*:*:*","cpe:2.3:a:surrealdb:surrealdb:3.0.0:alpha9:*:*:*:*:*:*","cpe:2.3:a:surrealdb:surrealdb:3.0.0:beta1:*:*:*:*:*:*","cpe:2.3:a:surrealdb:surrealdb:3.0.0:beta2:*:*:*:*:*:*"],"sourceDates":{"published":"2026-07-20T12:19:46.477","lastModified":"2026-07-22T19:41:01.317"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
