Note that the MIME type used when the actual file is served to the user's browser is not determined by MediaWikis MIME-detection: files are not served through MediaWiki, but directly by the web server. for now, see $wgAntivirus and $wgAntivirusSetup MIME types when downloading If you really want to allow even such dangerous files, you can hack the detectScript function in the UploadBase.php file to always return false. Note that the detection of HTML and JavaScript is rather broad, and may report false positives - this is so because the Microsoft Internet Explorer is known to interpret files that look like HTML, regardless of file extension or MIME type reported by the web server, which would lead to the site being vulnerable to cross-site scripting attacks. Notably, anything that looks like one of the following formats will be rejected, regardless of detected mime type or file extension: HTML, JavaScript, PHP, shell scripts. In addition, MediaWiki rejects all files that look like scripts that could be accidentally executed on either the web server or the user's browser.

The MIME type define file extensions that are allowed for a given mime type. To support extra mime types for uploads on your wiki, you can use the MimeMagicInit hook since MediaWiki 1.24. MediaWiki stores its default mime types and media types in MimeMap.php. Pending: how does this relate to $wgCheckFileExtensions ? MIME type validation You can also disable the MIME type check completely by setting $wgVerifyMimeType = false - note however that this is very insecure: arbitrary files can then be uploaded with a "harmless" file extension, but may possibly still get executed/interpreted in a harmful way on the client computer, or the web server. Note that this only works for some well known image types (see ), other files will be accepted without any additional checks! If no mime module is installed, and no external mime detector command is configured, MediaWiki relies on PHP's GD module to detect the mime type.
