CVE-2026-41732: VMware Spring For Apache Pulsar

High severity, CVSS 8.1. EPSS: 0.4% chance of exploitation in the next 30 days.

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 products

• VMware Spring For Apache Pulsar: from 1.1.0, before 1.1.18 (fixed in 1.1.18); from 1.2.0, before 1.2.17.1 (fixed in 1.2.17.1); from 2.0.0, before 2.0.6 (fixed in 2.0.6)
