CVE-2026-82526: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in SciPhi-AI R2R
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.

Technical Analysis
CVE-2026-82526 is a critical SQL injection vulnerability affecting SciPhi-AI R2R versions up to 3.6.6. The vulnerability exists in the vector index creation endpoint where the index name parameter is used unsafely in a CREATE INDEX statement. Due to lack of identifier quoting or allowlist validation, attackers can inject semicolon-separated SQL statements, allowing arbitrary DDL and DML execution with PostgreSQL superuser privileges. This enables full compromise of the database through unauthenticated access.
Potential Impact
An unauthenticated attacker can execute arbitrary SQL commands on the backend PostgreSQL database with superuser privileges. This can lead to unauthorized data access, modification, deletion, or complete database compromise. The vulnerability poses a critical risk to confidentiality, integrity, and availability of the affected system's data.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the vector index creation endpoint and monitor for suspicious activity. Avoid exposing the service to untrusted networks. Implement input validation or filtering on the index name parameter if possible.
