performanceTL;DR
Performance Plugin deserializes cached performance reports from build directories using Java serialization without restricting classes. An attacker with Item/Configure permission can place crafted serialized data that executes code on the Jenkins controller during report loading. The fix removes deserialization of cached performance reports.

You are affected if you are using a version that falls within the vulnerable range and users with Item/Configure permission can influence cached performance report files on the controller.
