GHSA-f8cc-g7j8-xxpm

Impact

The vulnerability may allow a remote attacker to terminate the application with a stack overflow error resulting in a denial of service only by manipulating the processed input stream.

Patches

XStream 1.4.20 handles the stack overflow and raises an InputManipulationException instead.

Workarounds

The only solution is to catch the StackOverflowError in the client code calling XStream.
