CVE-2026-82526 Details
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.
A stacked SQL injection vulnerability has been identified in R2R versions through 3.6.6. This vulnerability allows unauthenticated attackers to execute arbitrary SQL statements by manipulating the index name parameter in the vector index creation endpoint. The issue arises because the index name is directly interpolated into a CREATE INDEX statement using string formatting, without proper identifier quoting or allowlist validation. This oversight enables the execution of arbitrary Data Definition Language (DDL) and Data Manipulation Language (DML) statements, separated by semicolons, under the PostgreSQL superuser account.
To address this vulnerability, treat the index name and index column parameters as SQL identifiers by allowlisting them and applying proper quoting before interpolation into SQL statements. Additionally, require superuser privileges for the '/v3/indices' POST and DELETE endpoints, and set authentication requirements to true by default.
