Answer in brief
CVE-2026-41732 records a High severity (CVSS 8.1) vulnerability in In Spring for Apache Pulsar, overly broad trusted-package matching in header mapper exposes JDK classes to deserialization. The current sources do not mark it as known exploited. The current feed maps Spring/Spring for Apache Pulsar (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 8.1. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

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.
