| 描述 | The footerHtml branding field is served in the unauthenticated public siteConfig endpoint without HTML sanitization. While other branding fields like loginTagline and metaDescription are sanitized via strip_tags(), footerHtml receives only a (string) cast. AdminModel.php buildPublicSubset() at line 214: 'footerHtml' => (string)($config['branding']['footerHtml'] ?? ''). UserController.php siteConfig() serves this to unauthenticated users via /api/public/siteConfig.php. An admin can inject arbitrary HTML/JS. CSP blocks script tags but not event handlers (img onerror, svg onload). Requires admin privileges to inject. PoC: curl -s http://127.0.0.1:8080/api/public/siteConfig.php | jq .branding.footerHtml returns unsanitized HTML.
