Scala 2.13.x before 2.13.9 has a Java deserialization chain in its JAR file.
CRITICAL 9.8EPSS 8.25%
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (8.25%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
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.
