Advisory
Source description from Wordfence Intelligence, credited to TANG Cheuk Hei (siunam).
The Bit File Manager plugin for WordPress is vulnerable to Remote Code Execution in versions 6.0 to 6.5.5 via the 'checkSyntax' function. This is due to writing a temporary file to a publicly accessible directory before performing file validation. This makes it possible for unauthenticated attackers to execute code on the server if an administrator has allowed Guest User read permissions.
