## Overview

JsonPulsarHeaderMapper matched type headers against trusted packages using a prefix check, meaning that trusting any package implicitly trusted all of its subpackages. Additionally, an empty trusted-packages configuration fell back to trusting all packages rather than applying a safe default allow-list.

Affected versions:
Spring for Apache Pulsar 2.0.0 through 2.0.5; 1.2.0 through 1.2.17; 1.1.0 through 1.1.17.

## Affected

- `spring_for_apache_pulsar >= 1.1.0, < 1.1.18`
- `spring_for_apache_pulsar >= 1.2.0, < 1.2.17.1`
- `spring_for_apache_pulsar >= 2.0.0, < 2.0.6`

## Remediation

Upgrade past the affected range:

- `spring_for_apache_pulsar 2.0.6`
