Description
The Request a Quote for WooCommerce plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 2.9.2 via the `afrfq_submit_quote_via_popup()` function. This is due to missing file extension and MIME type validation in the popup upload handler, which uses the raw attacker-supplied filename directly as the destination for `move_uploaded_file()`. This makes it possible for unauthenticated attackers to upload executable files, such as PHP files, to a web-accessible temporary RFQ upload directory when a public quote rule with the multi-page popup flow is enabled.
