## Overview

Spring Data Relational does not properly escape binding values of externally-controlled input when using StringMatcher (STARTING, ENDING, or CONTAINING) in Query By Example (QBE). An attacker can supply wildcard characters to perform boolean-based blind data inference.

Affected versions:
Spring Data Relational/JDBC/R2DBC 4.0.0 through 4.0.5; 3.5.0 through 3.5.11; 3.4.0 through 3.4.14; 3.3.0 through 3.3.16; 3.2.0 through 3.2.15; 3.1.0 through 3.1.14; 3.0.0 through 3.0.15; 2.4.0 through 2.4.19.

## Affected

- `spring_data_relational < 2.4.20`
- `spring_data_relational >= 3.0.0, < 3.3.17`
- `spring_data_relational >= 3.4.0, < 3.4.15`
- `spring_data_relational >= 3.5.0, < 3.5.11.1`
- `spring_data_relational >= 4.0.0, < 4.0.5.1`

## Remediation

Upgrade past the affected range:

- `spring_data_relational 4.0.5.1`
