What the vulnerability does
The Alex Reservations: Smart Restaurant Booking plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the /wp-json/srr/v1/app/upload/file REST endpoint in all versions up to, and including, 2.2.3. This makes it possible for authenticated attackers, with Administrator-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.
Explanation of Vulnerability in Simple Terms
Alex Reservations: Smart Restaurant Booking versions 2.2.3 and earlier contain an unrestricted file upload vulnerability. An authenticated administrator can upload arbitrary files to the server, potentially including executable code. This allows an attacker with admin privileges to run their own code on the site and compromise the entire installation.
What an attacker can do
Upload and execute arbitrary files on the server, including malicious code.
Potential impact on your site
A compromised admin account can lead to full site takeover, data theft, and malware installation.
Conditions required to exploit
Attacker must have administrator-level access to the application.
