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.
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.
Cross-site scripting (XSS) vulnerability in Apache Wicket 1.4.x before 1.4.20 allows remote attackers to inject arbitrary web script or HTML via the wicket:pageMapName parameter.
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.
