Doc Type: If docs needed, set a value
Doc Text:
A flaw was found in Scala's LazyList that permits code execution during deserialization. This issue could allow an attacker to craft a LazyList containing a malicious Function0 call to execute arbitrary code on a server that deserializes untrusted data.

Description Avinash Hanwate 2022-09-26 10:23:36 UTC 
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 LazyList 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.
