Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache Wicket's wicket-util package is vulnerable to remote code execution in versions from 10.0.0-M1 before 10.1.0, from 9.0.0 before 9.18.0, and from 8.0.0 before 8.16.0. The default configuration of XSLTResourceStream is affected when it processes untrusted input without validation, which can allow an attacker to run code. Upgrade to version 10.1.0, 9.18.0 or 8.16.0, which fix the issue. The source gives few details on the exact attack conditions.
