Spring For Apache Pulsar
Monthly
Insecure deserialization in Spring for Apache Pulsar's JsonPulsarHeaderMapper allows remote attackers to bypass trusted-package controls and potentially trigger arbitrary Java object instantiation through Pulsar message headers. The flaw stems from a prefix-based package match plus an unsafe empty-allow-list default, affecting versions 1.1.0-1.1.17, 1.2.0-1.2.17, and 2.0.0-2.0.5. No public exploit identified at time of analysis, but the CVSS 8.1 rating and CWE-502 classification place this firmly in the high-impact Java deserialization category that has historically yielded remote code execution.
