By crafting a special URL it is possible to make Wicket deliver unprocessed HTML templates. This would allow an attacker to see possibly sensitive information inside a HTML template that is usually removed during rendering. Affected are Apache Wicket versions 7.16.0, 8.8.0 and 9.0.0-M5

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.

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.

Multiple cross-site scripting (XSS) vulnerabilities in the (1) RadioGroup and (2) CheckBoxMultipleChoice classes in Apache Wicket 1.5.x before 1.5.15, 6.x before 6.22.0, and 7.x before 7.2.0 allow remote attackers to inject arbitrary web script or HTML via a crafted "value" attribute in a <input> element.

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.

Unspecified vulnerability in Apache Wicket 1.4.x before 1.4.23, 1.5.x before 1.5.11, and 6.x before 6.8.0 allows remote attackers to obtain sensitive information via vectors that cause raw HTML templates to be rendered without being processed and reading the information that is outside of wicket:panel markup.

Cross-site scripting (XSS) vulnerability in Apache Wicket 1.4.x before 1.4.21 and 1.5.x before 1.5.8 allows remote attackers to inject arbitrary web script or HTML via vectors involving a %00 sequence in an Ajax link URL associated with a Wicket app.

Directory traversal vulnerability in Apache Wicket 1.4.x before 1.4.20 and 1.5.x before 1.5.5 allows remote attackers to read arbitrary web-application files via a relative pathname in a URL for a Wicket resource that corresponds to a null package.
