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.

Cross-site scripting (XSS) vulnerability in Apache Wicket 1.4.x before 1.4.22, 1.5.x before 1.5.10, and 6.x before 6.4.0 might allow remote attackers to inject arbitrary web script or HTML via vectors related to <script> tags in a rendered response.

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.

Dulwich before 0.18.5, when an SSH subprocess is used, allows remote attackers to execute arbitrary commands via an ssh URL with an initial dash character in the hostname, a related issue to CVE-2017-9800, CVE-2017-12836, CVE-2017-12976, CVE-2017-1000116, and CVE-2017-1000117.

In Apache Wicket 1.5.10 or 6.13.0, by issuing requests to special urls handled by Wicket, it is possible to check for the existence of particular classes in the classpath and thus check whether a third party library with a known security vulnerability is in use.

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.

The DiskFileItem class in Apache Wicket 6.x before 6.25.0 and 1.5.x before 1.5.17 allows remote attackers to cause a denial of service (infinite loop) and write to, move, and delete files with the permissions of DiskFileItem, and if running on a Java VM before 1.3.1, execute arbitrary code via a crafted serialized Java object.

Cross-site scripting (XSS) vulnerability in the getWindowOpenJavaScript function in org.apache.wicket.extensions.ajax.markup.html.modal.ModalWindow in Apache Wicket 1.5.x before 1.5.15, 6.x before 6.22.0, and 7.x before 7.2.0 might allow remote attackers to inject arbitrary web script or HTML via a ModalWindow title.
