We have updated the .htaccess that ships with our kits to the new version 2023-07-22, which adds protection against browser MIME type detection from malicious file uploads for files that have already been copied to the media folder. We recommend to update your sites’ .htaccess or server configuration with the new changes if you might have potential attackers in your group of authenticated Panel users or if your sites allow file uploads by visitors and the file extensions of uploaded files are not limited to a fixed safe list.
Thanks to Shankar Acharya (@5hank4r) for making us aware of this potential attack vector.
Frame-blocking in the Panel
The Panel now sends the Content-Security-Policy: frame-ancestors 'none' header to increase the protection against clickjacking attacks. The session cookie was already set to SameSite before, so this is an additional layer of protection.
Thanks to Shankar Acharya (@5hank4r) for suggesting this security enhancement.
Security-related breaking changes
All users are logged out from their sessions after updating to this patch release.
The Xml data handler (e.g. Data::decode($string, 'xml')) and the Xml::parse() method no longer process XML external entities.
The Panel can no longer be embedded in HTML frames.
