What kind of vulnerability is it? Who is impacted?
This is a disclosure for a security vulnerability in the SparseMatrix class. The vulnerability is a deserialization issue that
can lead to a wide range of privilege escalations depending on the circumstances. The problematic area is the read method
of the SparseMatrix class.
This method takes in an InputStream and returns a SparseMatrix object. We consider this to be a method that can be
exposed to untrusted input in at least two use cases:
InputStream and the application parses it into
a SparseMatrix. This can be a multi-tenant application that hosts many different users perhaps with different privilege
levels.InputStream from external sources.You are vulnerable if you import non-controlled serialized SparseMatrix objects.

Is there a way for users to fix or remediate the vulnerability without upgrading?
Do not use SparseMatrix deserialization (SparseMatrix.read(...) methods).
