What is Ehcache? Ehcache is an open source, standards-based cache that boosts performance, offloads your database, and simplifies scalability.

Vulnerability details: A vulnerability in the FasterXML jackson-databind library could allow an unauthenticated remote attacker to execute arbitrary code on the target system. This defect exists because the source code file of the affected software incorrectly handles the default type when using Ehcache. An attacker could exploit this vulnerability by sending a request to submit a malicious input to the target system to execute arbitrary code.
