Technical Analysis
CVE-2026-104069 describes a remote code execution vulnerability in danielbrendel's hortusfox-web prior to version 6.2. The vulnerability exists because the ThemeModule::startImport() method extracts uploaded ZIP archives directly into the public web root before validating file names, extensions, or content. An authenticated administrator can exploit this by uploading a specially crafted theme archive containing a PHP file and an .htaccess file that re-enables execution of PHP scripts. This enables execution of arbitrary OS commands with the privileges of the web server user.
Potential Impact
Successful exploitation allows an authenticated administrator to execute arbitrary operating system commands on the server as the web-server user. This can lead to full compromise of the affected web application environment.
Mitigation Recommendations
A fix is available in hortusfox-web version 6.2 and later. Users should upgrade to version 6.2 or above to remediate this vulnerability. Until then, restrict administrator access and avoid uploading untrusted theme archives.
