Threats Tagged 'cve-2026-76982'

CVE-2026-76982 is a vulnerability in Apache Wicket where improper neutralization of input occurs during web page generation. Specifically, the Button component when rendered as a <button> element writes its model object into the element body without encoding it, allowing markup in the model to be rendered as HTML. This affects Apache Wicket versions from 8.0.0 through 8.18.0, 9.0.0 through 9.23.0, and 10.0.0 through 10.10.0, as well as older unsupported releases from 6.25.0 and 7.5.0 onwards. The issue can be mitigated by upgrading to versions 8.19.0, 9.24.0, or 10.11.0 or by calling setEscapeModelStrings(true) on affected buttons as a workaround.

CVE-2026-76982 is a 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 because the Button component clears the escape-model-strings flag for attribute encoding but does not encode the element body when rendering a <button> element, allowing unescaped markup from the model to be rendered. This can lead to XSS if an attacker can influence the model data rendered inside a <button> element. The vulnerability affects Button and its subclasses AjaxButton, AjaxFallbackButton, and WizardButton. Users are recommended to upgrade to fixed versions 8.19.0, 9.24.0, or 10.11.0.
