| Titre | Krayin Krayin CRM ≤ 2.2.5 Cross Site Scripting |
|---|
| Description | A stored cross-site scripting (XSS) vulnerability in the TinyMCE media upload functionality of Krayin CRM through 2.2.5 allows an authenticated user with upload permissions to bypass SVG sanitization by uploading SVG content with a non-SVG client filename. The application relies on the client-controlled file extension when deciding whether to sanitize the content, allowing malicious SVG files containing JavaScript to be stored and served from the public storage directory, resulting in arbitrary JavaScript execution in the application origin. |
