Zend-Navigation vulnerable to Cross-site Scripting
Date: 2024-06
Affected: composer/zendframework/zend-navigation, composer/zendframework/zend-navigation
Attack vector: xss
Category: vulnerability-disclosure
Severity: High
CWE: CWE-352
CWE-79
CVSS: 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N)

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\Form` view helpers. - Most `Zend\Navigation` (aka `Zend\View\Helper\Navigation\*`) view helpers. - All "HTML Element" view helpers: `htmlFlash()`, `htmlPage()`, `htmlQuickTime()`. - `Zend\View\Helper\Gravatar`
