R2R 3.6.6 lets attackers run database commands

CVE-2026-82526 · published today
Summary

Versions of R2R up to 3.6.6 let anyone send a specially crafted request to the vector index creation feature and cause the system to execute any database command it wants. Because the request does not require a login, an attacker could add, change, or delete data and even take control of the database. Upgrade to a newer R2R release that fixes the problem, and restrict access to the index‑creation endpoint with authentication or network controls until the patch is applied.

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.
