{"id":"CVE-2025-15022","state":"PUBLISHED","title":"Cross-site scripting in Action caption","description":"Action captions in Vaadin accept HTML by default but were not sanitized, potentially allowing Cross-site Scripting (XSS) if caption content is derived from user input.\n\nIn Vaadin Framework 7 and 8, the Action class is a general-purpose class that may be used by multiple components.
