AnalysisAIv1 – Jul 28, 2026

Unauthenticated remote attackers can partially read and modify data in Apache Wicket versions 9.0.0 through 9.23.0 and 10.0.0 through 10.9.0 due to a protection mechanism that relies on insufficiently random values. The vulnerability is automatable with low attack complexity and no user interaction, though no active exploitation or public exploit code has been observed at this time. While the technical impact is limited to partial confidentiality and integrity compromise, the widespread enterprise use of Wicket makes it a moderate priority for patching.
