In Apache wicket-jquery-ui <= 6.29.0, <= 7.10.1, <= 8.0.0-M9.1, JS code created in WYSIWYG editor will be executed on display.

In Wicket jQuery UI 6.28.0 and earlier, 7.9.1 and earlier, and 8.0.0-M8 and earlier, a security issue has been discovered in the WYSIWYG editor that allows an attacker to submit arbitrary JS code to WYSIWYG editor.

Apache Wicket before 1.5.12, 6.x before 6.17.0, and 7.x before 7.0.0-M3 might allow remote attackers to obtain sensitive information via vectors involving identifiers for storing page markup for temporary user sessions.

Apache Wicket 6.x before 6.25.0, 7.x before 7.5.0, and 8.0.0-M1 provide a CSRF prevention measure that fails to discover some cross origin requests. The mitigation is to not only check the Origin HTTP header, but also take the Referer HTTP header into account when no Origin was provided. Furthermore, not all Wicket server side targets were subjected to the CSRF check. This was also fixed.

Apache Wicket before 1.5.13, 6.x before 6.19.0, and 7.x before 7.0.0-M5 make it easier for attackers to defeat a cryptographic protection mechanism and predict encrypted URLs by leveraging use of CryptoMapper as the default encryption provider.
