CVE-2026-41732
In Spring for Apache Pulsar, overly broad trusted-package matching in header mapper exposes JDK classes to deserialization
Description
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.

Action Type Old Value New Value Added Translation Title: Spring for Apache Pulsar de Spring, Description: JsonPulsarHeaderMapper comparaba los encabezados de tipo con paquetes de confianza utilizando una comprobación de prefijo, lo que significa que confiar en cualquier paquete implicaba confiar implícitamente en todos sus subpaquetes. Además, una configuración vacía de trusted-packages recurría a confiar en todos los paquetes en lugar de aplicar una lista de permitidos predeterminada segura.
