CVE-2026-75802Network attack vectorHinoki check available

Cross-site scripting via unescaped editable-label display values

Published Aug 31, 2026 · Updated Aug 31, 2026

Cross-site scripting in Apache Wicket 8.0.0 through 8.18.0, 9.0.0 through 9.23.0, and 10.0.0 through 10.10.0 allows attackers to run script. The editable-label components insert renderer display values and overridden defaultNullLabel output into label markup without HTML escaping. Exploitation requires attacker-influenced choice or model data and a user who views the affected label; script then executes in that user's browser.
