{"id":"GHSA-m464-hj36-96vx","summary":"Duplicate Advisory: SurrealDB has Denial of Service in JSON parser due to nested objects","details":"## Duplicate Advisory\n\nThis advisory has been withdrawn because it is a duplicate of GHSA-q729-696q-g9pq. This link is maintained to preserve external references.\n\n## Original Description\nSurrealDB before 3.1.0 fails to enforce the configured recursion depth limit in the value and JSON parser when processing nested braces, brackets, or parentheses. Unauthenticated attackers can send deeply nested JSON payloads to the WebSocket /rpc endpoint to exhaust server memory and crash the process.","modified":"2026-09-04T21:00:07.457567632Z","published":"2026-07-20T12:33:11Z","withdrawn":"2026-09-04T20:47:44Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2026-09-04T20:47:44Z","nvd_published_at":"2026-07-20T12:19:46Z","cwe_ids":["CWE-674"],"severity":"HIGH"},"references":[{"type":"WEB","url":"https://github.com/surrealdb/surrealdb/security/advisories/GHSA-q729-696q-g9pq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-63760"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/surrealdb-before-denial-of-service-via-json-parser"}],"affected":[{"package":{"name":"surrealdb","ecosystem":"crates.io","purl":"pkg:cargo/surrealdb"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}],"database_specific":{"last_known_affected_version_range":"\u003c 3.1.0","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/07/GHSA-m464-hj36-96vx/GHSA-m464-hj36-96vx.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/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"}]}
