This vulnerability can lead to malicious scripts being executed in the browsers of all site visitors, posing a significant security risk.

Original NVD Description

Emlog is an open source website building system. In versions 2.6.29 and prior, article content is processed by Parsedown without enabling safe mode, which means raw HTML including <script> tags embedded in Markdown is passed through unescaped. The output is rendered with no additional sanitization, resulting in stored XSS visible to all site visitors. At time of publication, there are no publicly known patches.
