CVE-2020-24164
A deserialization flaw is present in Taoensso Nippy before 2.14.2.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.11%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
A deserialization flaw is present in Taoensso Nippy before 2.14.2. In some circumstances, it is possible for an attacker to create a malicious payload that, when deserialized, will allow arbitrary code to be executed. This occurs because there is automatic use of the Java Serializable interface.
