Source record

Technical description

The get_allowed_mime_types function in wp-includes/functions.php in WordPress before 3.6.1 does not require the unfiltered_html capability for uploads of .htm and .html files, which might make it easier for remote authenticated users to conduct cross-site scripting (XSS) attacks via a crafted file.

NVD vector: AV:N/AC:M/Au:N/C:N/I:P/A:N
