What is CVE-2026-59274?

The UnZipTransformer in Spring Integration lacks proper limitations on the size and count of entries when processing zip archives. This oversight allows attackers to craft zip files that can overwhelm the Java Virtual Machine (JVM) heap memory, potentially resulting in a denial-of-service situation. Users of affected Spring Integration versions should apply available patches to mitigate this risk.

Affected Version(s)

Spring Integration 7.1.0

Spring Integration 7.0.0 <= 7.0.5

Spring Integration 6.5.0 <= 6.5.10
