## Overview

Spring Data MongoDB repository query methods annotated with @Query that use regex parameter binding perform insufficient validation of the bound parameter. An attacker can supply a crafted string to break out of the intended regular expression quoting.

Affected versions:
Spring Data MongoDB 5.0.0 through 5.0.5; 4.5.0 through 4.5.11; 4.4.0 through 4.4.14; 4.3.0 through 4.3.16; 4.2.0 through 4.2.15; 4.1.0 through 4.1.14; 4.0.0 through 4.0.15; 3.4.0 through 3.4.19.

## Affected

- `spring_data_mongodb >= 3.4.0, < 3.4.20`
- `spring_data_mongodb >= 4.0.0, <= 4.0.15`
- `spring_data_mongodb >= 4.1.0, <= 4.1.14`
- `spring_data_mongodb >= 4.2.0, <= 4.2.15`
- `spring_data_mongodb >= 4.3.0, < 4.3.17`
- `spring_data_mongodb >= 4.4.0, < 4.4.15`
- `spring_data_mongodb >= 4.5.0, < 4.5.11.1`
- `spring_data_mongodb >= 5.0.0, < 5.0.5.1`

## Remediation

Upgrade past the affected range:

- `spring_data_mongodb 5.0.5.1`
