Lifecycle Timeline
5DescriptionCVE.org
A security flaw has been discovered in Casdoor 2.356.0. This affects the function dangerouslySetInnerHTML. Performing a manipulation of the argument formCss/formCssMobile/formSideHtml results in cross site scripting. The attack can be initiated remotely. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
AnalysisAI
Stored cross-site scripting (XSS) in Casdoor 2.356.0 via the dangerouslySetInnerHTML function allows authenticated remote attackers to inject malicious scripts through the formCss, formCssMobile, or formSideHtml parameters. An attacker with authenticated access can craft payloads that execute arbitrary JavaScript in the context of other users' browsers when they view affected forms. Publicly available exploit code exists for this vulnerability, and the vendor has not responded to early disclosure attempts, indicating no coordinated patch timeline.
Technical ContextAI
The vulnerability stems from unsafe use of the dangerouslySetInnerHTML React function without proper input sanitization on user-controlled CSS and HTML parameters. The CWE-79 classification confirms this is a cross-site scripting flaw where untrusted user input is rendered directly as HTML/CSS without encoding or validation. The affected parameters (formCss, formCssMobile, formSideHtml) are form configuration fields that accept styling or markup, but the application fails to sanitize these inputs before passing them to dangerouslySetInnerHTML, allowing style-based or script-based XSS payloads to execute. This is particularly dangerous in authentication/form contexts where user sessions may be hijacked or credentials stolen.
RemediationAI
No vendor-released patch identified at time of analysis. The vendor did not respond to early disclosure attempts. Users should immediately audit form configuration permissions and restrict access to formCss, formCssMobile, and formSideHtml parameters to trusted administrators only. As a temporary mitigation, implement Content Security Policy (CSP) headers to restrict inline script execution and disable script-src for user-controlled content. Input validation should be enforced server-side to reject or sanitize any CSS or HTML containing script tags, event handlers (onclick, onload, etc.), or suspicious Unicode/encoding patterns. Monitor Casdoor's GitHub repository and security advisories for any future patch releases. Consider migrating to alternative form builders if Casdoor does not address this vulnerability within your organization's acceptable timeframe.
