Description

A Java Serialization vulnerability was found in Apache Tapestry 4. Apache Tapestry 4 will attempt to deserialize the "sp" parameter even before invoking the page's validate method, leading to deserialization without authentication.

Users of Apache Tapestry 4 should upgrade to the latest Apache Tapestry 5 version.
