Authenticated SQL injection via unescaped filter values
Published Mar 18, 2026 · Updated Mar 18, 2026
SQL injection in Spring AI's MariaDB converter 1.0.0 through 1.0.3 and 1.1.0 through 1.1.2 allows remote authenticated users to execute SQL. MariaDBFilterExpressionConverter wraps filter strings in quotes without escaping them, then similarity search and deletion paths splice the predicate into SQL. Applications are exposed when low-privileged users can influence MariaDB metadata filters, enabling restricted-document reads or vector-store deletion.

Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=1.0.x <1.0.4
- Affected versionversion=1.1.x <1.1.3
