Unspecified vulnerability in the Trackback functionality in DotClear 1.2.1 has unknown impact and attack vectors.

Dotclear 2.29 Remote Code Execution via Authenticated File Upload

Dotclear 2.29 contains a remote code execution vulnerability that allows authenticated attackers to upload malicious PHP files through the media upload functionality. Attackers can exploit the file upload process by crafting a PHP shell with a command execution form to gain system access through the uploaded file.

Dotclear 2.25.3 Authenticated Remote Code Execution via File Upload

Dotclear 2.25.3 contains a remote code execution vulnerability that allows authenticated attackers to upload malicious PHP files with .phar extension through the blog post creation interface. Attackers can upload files containing PHP system commands that execute when the uploaded file is accessed, enabling arbitrary code execution on the server.

A Reflected Cross-Site Scripting (XSS) vulnerability has been identified in Dotclear version 2.29. The flaw exists within the Search functionality of the Admin Panel.

XSS was discovered in Dotclear v2.11.2, affecting admin/blogs.php and admin/users.php with the sortby and order parameters.
