Although a single loop's iteration count is constrained, nesting multiple loops (e.g., each with 1,000,000 iterations) is not, so an attacker can execute a function that consumes all server CPU time. Configured timeouts do not stop the execution, rendering the server unresponsive to other queries and connections until it is manually restarted.","state":0,"publishedAt":"2026-07-18T14:17:11.22+00:00","modifiedAt":"2026-09-29T19:10:00.16+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · disclosure@vulncheck.com · Secondary","vector":"CVSS:4.0/AV:N/AC:L/AT:N/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":7.1,"severity":"HIGH"},{"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-pxw4-94j3-v9pf","https://www.vulncheck.com/advisories/surrealdb-before-cpu-exhaustion-via-nested-for-loops"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2025-71397","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-835"],"productCriteria":["cpe:2.3:a:surrealdb:surrealdb:*:*:*:*:*:*:*:*"],"sourceDates":{"published":"2026-07-18T14:17:11.220","lastModified":"2026-09-29T19:10:00.160"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
