What it is

The UnZipTransformer does not limit decompressed entry size or entry count when processing archives. Consequently, an attacker can send a zip archive that can exhaust JVM heap memory, causing a denial-of-service outage.

Spring Integration 7.0.0 - 7.0.5

Spring Integration 6.5.0 - 6.5.10
