Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache Causeway versions before 3.5.0 (causeway-commons, causeway-applib, causeway-core and causeway-viewer-wicket) are vulnerable to Java deserialization through user-controllable URL parameters. An authenticated attacker may be able to execute arbitrary code with the application's privileges. Upgrade to version 3.5.0, which fixes the issue.
