An Improper Input Validation vulnerability was discovered in Apache Hop Engine versions before 2.8.0. The vulnerability was identified by security researcher Jonathan Leitschuh and disclosed on March 18, 2024. The issue specifically affects the Hop Server component when writing links to the PrepareExecutionPipelineServlet page, where the 'id' parameter was not properly escaped in the HTML generation process (Apache Security).
The vulnerability stems from improper escaping of the 'id' parameter when the Hop Server writes links to the PrepareExecutionPipelineServlet page. This parameter is not directly accessible by users creating pipelines, which contributes to its low severity assessment. The issue is confined to the Hop Server component and does not directly impact the client-side functionality (Apache Security).
The impact of this vulnerability is considered low due to the limited accessibility of the affected parameter. The vulnerability only affects users utilizing the Hop Server component, with no direct impact on client-side operations (Apache Security).
Users are recommended to upgrade to Apache Hop Engine version 2.8.0, which contains the fix for this vulnerability. This version addresses the improper input validation issue by implementing proper escaping for the 'id' parameter (Apache Security).
