Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Apache Commons Configuration (commons-configuration2) versions from 2.0 before 2.10.1 are vulnerable. When ListDelimiterHandler.flatten(Object, int) is called with a cyclical object tree, it can raise a StackOverflowError. The source gives few details on the attacker's position or what the impact is beyond this error, and it describes the issue as an out-of-bounds write. Users should upgrade to commons-configuration2 version 2.10.1, which fixes the issue.
