The HTML filter and csv-file search plugin for WordPress is vulnerable to Local File Inclusion in versions up to, and including, 2.7 via the src attribute of the csvsearch shortcode. This allows authenticated attackers, with contributor-level permissions and above, to include and execute arbitrary files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where images and other “safe” file types can be uploaded and included.
The product makes files or directories accessible to unauthorized actors, even though they should not be.

Web servers, FTP servers, and similar servers may store a set of files underneath a “root” directory that is accessible to the server’s users. Applications may store sensitive files underneath this root without also using access control to limit which users may request those files, if any. Alternately, an application might package multiple files or directories into an archive file (e.g., ZIP or tar), but the application might not exclude sensitive files that are underneath those directories. In cloud technologies and containers, this weakness might present itself in the form of misconfigured storage accounts that can be read or written by a public or anonymous user.
