## Description

Scala 2.13.x before 2.13.9 has a Java deserialization chain in its JAR
file. On its own, it cannot be exploited. There is only a risk in
conjunction with Java object deserialization within an application. In such
situations, it allows attackers to erase contents of arbitrary files, make
network connections, or possibly run arbitrary code (specifically,
Function0 functions) via a gadget chain.
