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.

Taoensso Sente version Prior to version 1.14.0 contains a Cross Site Request Forgery (CSRF) vulnerability in WebSocket handshake endpoint that can result in CSRF attack, possible leak of anti-CSRF token. This attack appears to be exploitable via malicious request against WebSocket handshake endpoint. This vulnerability appears to have been fixed in 1.14.0 and later.
