CVE-2026-59322: VMware Spring Integration

Medium severity, CVSS 6.3. EPSS: 0.3% chance of exploitation in the next 30 days.

The EmbeddedHeadersJsonMessageMapper defaults to an overly permissive header parsing posture in its constructor. When decodeNativeFormat processes raw byte payloads, it deserializes embedded JSON headers into a plain Map and constructs a GenericMessage with MutableMessageHeaders without sanitizing or filtering untrusted header names by default. Spring Integration 7.1.0 Spring Integration 7.0.0 - 7.0.5 Spring Integration 6.5.0 - 6.5.10 Spring Integration 6.4.0 - 6.4.12 Spring Integration 5.5.21 and earlier

Affected products

• VMware Spring Integration: before 5.5.22 (fixed in 5.5.22); from 6.4.0, before 6.4.13 (fixed in 6.4.13); from 6.5.0, before 6.5.11 (fixed in 6.5.11); from 7.0.0, before 7.0.5.1 (fixed in 7.0.5.1); from 7.1.0, before 7.1.0.1 (fixed in 7.1.0.1)
