## Overview

Spring Data REST is vulnerable to SpEL expression injection through map-typed properties when processing JSON Patch (application/json-patch+json) requests. When a persistent entity exposes a Map-typed property, the JSON Pointer path segment used as the map key is embedded directly into a SpEL expression without sanitization or validation.

Affected versions:
Spring Data REST 3.7.0 through 3.7.19; 4.3.0 through 4.3.16; 4.4.0 through 4.4.14; 4.5.0 through 4.5.11; 5.0.0 through 5.0.5.

## Affected

- `spring_data_rest >= 3.7.0, < 3.7.20`
- `spring_data_rest >= 4.3.0, < 4.3.17`
- `spring_data_rest >= 4.4.0, < 4.4.15`
- `spring_data_rest >= 4.5.0, < 4.5.11.1`
- `spring_data_rest >= 5.0.0, < 5.0.5.1`

## Remediation

Upgrade past the affected range:

- `spring_data_rest 5.0.5.1`
