Security readout for executives and security teams
Fastjson versions before 1.2.48 can mishandle JSON containing an @type value and may invoke Java class methods in unsafe ways. In some cases, this can lead to JNDI injection and full compromise. The CVE source says it was exploited in the wild from 2023 through 2025. Java applications are most likely exposed if they parse untrusted JSON with Alibaba Fastjson before 1.2.48, including shaded or bundled copies. Internet-facing APIs, message consumers, and services ingesting partner-supplied JSON deserve priority review. Treat this as urgent where legacy Fastjson handles untrusted input. The CVSS score is 10, impact can be complete compromise, and the source bundle states real-world exploitation. Prioritize internet-facing Java services first. Mitigation focus: Inventory applications and dependencies for Alibaba Fastjson before 1.2.48.; Upgrade affected Fastjson deployments to vendor-guided fixed or supported versions.; Review later Fastjson advisories, including the noted CVE-2022-25845 bypass..
