What the vulnerability does
The Custom WooCommerce Checkout Fields Editor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the save_wcfe_options function in all versions up to, and including, 1.3.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Explanation of Vulnerability in Simple Terms
Custom WooCommerce Checkout Fields Editor versions up to 1.3.1 contain a stored cross-site scripting (XSS) vulnerability. An authenticated user with low privileges can inject malicious scripts into checkout field configurations. These scripts execute in the browsers of other site visitors and administrators, potentially stealing session tokens or performing unauthorized actions on their behalf.
What an attacker can do
Inject malicious scripts that run in other users' browsers when they view checkout pages.
Potential impact on your site
Customers and admins visiting checkout pages may have their sessions hijacked or be tricked into performing unwanted actions.
Conditions required to exploit
Attacker must have a low-privilege authenticated account on the site (e.g., customer or contributor role).
