Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache Hop Engine versions before 2.8.0 are vulnerable to improper input validation. When Hop Server writes links to the PrepareExecutionPipelineServlet page, the "id" parameter is not properly escaped. The source describes the risk as low, since users who create pipelines cannot directly control this value, and it affects only the Hop Server component. Upgrade to Apache Hop Engine 2.8.0, which fixes the issue.
