See how inpost compares to other vendors in security performance
The InPost PL WordPress plugin before 1.9.1 does not verify that the request originates from the legitimate buyer before allowing the WooCommerce order parcel-locker destination to be updated, allowing unauthenticated attackers to silently redirect the shipping destination of any pending or processing order on the site.
Unauthenticated SQL Injection in InPost Gallery <= 2.1.4.6 versions.
The InPost for WooCommerce plugin and InPost PL plugin for WordPress are vulnerable to unauthorized access and deletion of data due to a missing capability check on the 'parserequest' function in all versions up to, and including, 1.4.0 (for InPost for WooCommerce) as well as 1.4.4 (for InPost PL). This makes it possible for unauthenticated attackers to read and delete arbitrary files on Windows servers. On Linux servers, only files within the WordPress install will be deleted, but all files can be read.
The The InPost Gallery plugin for WordPress is vulnerable to arbitrary shortcode execution via the inpostgallerygetshortcodetemplate AJAX action in all versions up to, and including, 2.1.4.2. This is due to the software allowing users to execute an action that does not properly validate a value before running doshortcode. This makes it possible for authenticated attackers, with Subscriber-level access and above, to execute arbitrary shortcodes.
