GHSA-gvpp-6jrj-5pqc: Zend-Form vulnerable to Cross-site Scripting
Many Zend Framework 2 view helpers were using the escapeHtml() view helper in order to escape HTML attributes, instead of the more appropriate escapeHtmlAttr(). In situations where user data and/or JavaScript is used to seed attributes, this can lead to potential cross site scripting (XSS) attack vectors.
Vulnerable view helpers include:
- All
Zend\Formview helpers. - Most
Zend\Navigation(akaZend\View\Helper\Navigation\*) view helpers. - All “HTML Element” view helpers:
htmlFlash(),htmlPage(),htmlQuickTime(). Zend\View\Helper\Gravatar
