CVE-2025-25197: Silverstripe Elemental enables XSS attacks in elemental "Content blocks in use" reports
Description

An elemental block can include an XSS payload, which can be executed when viewing the "Content blocks in use" report. The vulnerability is specific to that report and is a result of failure to cast input prior to including it in the grid field. This vulnerability is fixed in 5.3.12.
