Stored cross-site scripting vulnerability available via svg file uploads due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the svg file. By default, this can only be exploited by administrators, but the ability to upload svg files can be extended to authors.
