What the vulnerability does
01Description
The BFG Tools – Extension Zipper plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 1.0.7. This is due to insufficient input validation on the user-supplied `first_file` parameter in the `zip()` function. This makes it possible for authenticated attackers, with Administrator-level access and above, to read the contents of arbitrary files and directories outside the intended `/wp-content/plugins/` directory, which can contain sensitive information such as wp-config.php.

BFG Tools – Extension Zipper versions 1.0.7 and earlier contain a path traversal vulnerability that allows high-privilege users to read arbitrary files from the server. An attacker with administrative access can bypass directory restrictions and access sensitive files outside the intended scope. This affects confidentiality but not integrity or availability.
