Alone – Charity Multipurpose Non-profit WordPress Theme <= 7.8.5 - Missing Authorization to Unauthenticated Arbitrary File Deletion

The Alone – Charity Multipurpose Non-profit WordPress Theme theme for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the alone_import_pack_restore_data() function in all versions up to, and including, 7.8.5. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). This was partially patched in 7.8.5 and has been fully addresses in 7.8.7.

Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. Classes like this one can leave something behind, so the staged malware scanner is the second half: it looks for dropped files and modified code rather than for the request that created them. None of that substitutes for the fix: Alone 7.8.7 closes this, and updating the theme is the step that ends it.
