## Description

Pivotal Spring Framework through 5.3.16 suffers from a potential remote
code execution (RCE) issue if used for Java deserialization of untrusted
data. Depending on how the library is implemented within a product, this
issue may or not occur, and authentication may be required. NOTE: the
vendor's position is that untrusted data is not an intended use case. The
product's behavior will not be changed because some users rely on
deserialization of trusted data.
