脆弱性タイトル
SurrealDB before 3.1.0 Permission Bypass via WHERE Clause
ソース: CVE Program / CVE List V5
脆弱性説明
SurrealDB before 3.1.0 evaluates user-supplied WHERE clauses in SELECT statements (and SET/MERGE/CONTENT/PATCH clauses in UPDATE, UPSERT, INSERT ON DUPLICATE KEY UPDATE, and RELATE update-variant statements) against full record data before enforcing PERMISSIONS FOR SELECT WHERE restrictions. An authenticated user — including Record and Scope users — can exploit this ordering flaw to read the full contents of any table in the database they are authenticated against, bypassing table-level permission checks. Exfiltration is most direct when scripting functions are enabled (--allow-scripting), but is also possible via SurrealQL's THROW statement and timing-based side channels without scripting. The vulnerability is confined to the attacker's current database and does not cross namespace or database isolation boundaries.

SurrealDB 授权问题漏洞
ソース: CNNVD (China National Vulnerability Database)
脆弱性説明
surrealdb是SurrealDB公司开源的一个文档图数据库。 SurrealDB 3.1.0之前版本存在授权问题漏洞，该漏洞源于在处理用户提供的WHERE子句时存在顺序问题，在强制执行PERMISSIONS FOR SELECT WHERE限制之前，会针对完整记录数据进行评估，可能导致已认证用户绕过表级权限检查，读取其所认证数据库中任何表的全部内容。
