Threats affecting pkg:maven/org.apache.wicket/wicket-extensions

CVE-2026-83539 is a cross-site scripting (XSS) vulnerability in Apache Wicket's SmartLinkLabel and SmartLinkMultiLineLabel components. These components convert URLs found in text into clickable links without restricting URL schemes, allowing potentially malicious script execution when a user activates such a link. The vulnerability affects Apache Wicket versions 8.0.0 through 8.19.0, 9.0.0 through 9.24.0, and 10.0.0 through 10.11.0. Default Content-Security-Policy (CSP) in versions 9.x and 10.x mitigates this risk by restricting script execution, but applications that weaken or disable CSP are fully vulnerable. Version 8.x lacks CSP support and is fully affected. Fixed versions are 8.20.0, 9.25.0, and 10.12.0.

CVE-2026-76985 is a medium severity cross-site scripting (XSS) vulnerability in Apache Wicket affecting versions from 8.0.0 through 8.18.0, 9.0.0 through 9.23.0, and 10.0.0 through 10.10.0. The issue arises when applications override certain methods to add additional attributes to <option> tags in a Palette component without properly escaping attacker-controlled input. This improper neutralization can lead to XSS attacks. Fixed versions are 8.19.0, 9.24.0, and 10.11.0.

Apache Wicket contains a cross-site scripting (XSS) vulnerability in AjaxEditableChoiceLabel and related components where HTML escaping is not applied to certain display values. This allows an attacker who can influence the choice or model data to inject malicious scripts that execute in the browser of users viewing the affected pages. The issue affects multiple versions of Apache Wicket and is fixed in versions 8.19.0, 9.24.0, and 10.11.0.
