CVE-2026-82526— R2R 3.6.6 SQL Injection via Vector Index Creation Endpoint

Quick assessment

Affected
SciPhi-AI R2R
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

R2R 版本 3.6.6 及更早版本存在一个堆叠式 SQL 注入漏洞，允许未经认证的通过操纵向量索引创建接口中的索引名参数来执行任意 SQL 语句。由于该索引名直接通过字符串格式化插入到 CREATE INDEX 语句中，且未对标识符进行引号包裹或白名单校验，因此在 PostgreSQL 超级用户权限下，攻击者可以利用分号分隔的语句执行任意 DDL 和 DML 操作。

Vulnerability Title
R2R 3.6.6 SQL Injection via Vector Index Creation Endpoint
Source: CVE Program / CVE List V5
Vulnerability Description
R2R through 3.6.6 contains a stacked SQL injection vulnerability that allows unauthenticated attackers to execute arbitrary SQL statements by manipulating the index name parameter in the vector index creation endpoint. The index name is interpolated directly into a CREATE INDEX statement via string formatting without identifier quoting or allowlist validation, enabling arbitrary DDL and DML execution through semicolon-separated statements under the PostgreSQL superuser account.
