Any user able to execute arbitrary queries \u2014 including unauthenticated guests when --allow-guests is enabled \u2014 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."}], "problemTypes": [{"descriptions": [{"lang": "en", "description": "NULL Pointer Dereference", "cweId": "CWE-476", "type": "CWE"}]}], "affected": [{"vendor": "surrealdb", "product": "surrealdb", "defaultStatus": "unaffected", "packageURL": "pkg:cargo/SurrealDB", "versions": [{"version": "0", "status": "affected", "versionType": "semver", "lessThan": "2.6.1"}, {"version": "2.6.1", "status": "unaffected", "versionType": "semver"}]}, {"vendor": "surrealdb", "product": "surrealdb", "defaultStatus": "unaffected", "packageURL": "pkg:cargo/SurrealDB", "versions": [{"version": "0", "status": "affected", "versionType": "semver", "lessThan": "3.0.0-beta.3"}, {"version": "3.0.0-beta.3", "status": "unaffected", "versionType": "semver"}]}], "metrics": [{"format": "CVSS", "cvssV4_0": {"version": "4.0", "vectorString": "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", "attackVector": "NETWORK", "attackComplexity": "LOW", "attackRequirements": "PRESENT", "privilegesRequired": "LOW", "userInteraction": "NONE", "vulnConfidentialityImpact": "NONE", "vulnIntegrityImpact": "NONE", "vulnAvailabilityImpact": "HIGH", "subConfidentialityImpact": "NONE", "subIntegrityImpact": "NONE", "subAvailabilityImpact": "NONE", "baseScore": 6, "baseSeverity": "MEDIUM"}}], "references": [{"url": "https://github.com/surrealdb/surrealdb/security/advisories/GHSA-xx7m-69ff-9crp", "name": "GitHub Security Advisory (GHSA-xx7m-69ff-9crp)", "tags": ["vendor-advisory"]}, {"name": "VulnCheck Advisory: SurrealDB before v2.6.1 Denial of Service via scripting", "tags": ["third-party-advisory"], "url": "https://www.vulncheck.com/advisories/surrealdb-before-denial-of-service-via-scripting"}], "credits": [{"lang": "en", "value": "LucyEgan", "type": "reporter"}], "x_generator": {"engine": "vulncheck-endgame"}}}}
