e-Commerce Plugin - Security Vulnerability (CVE-2026-120597)

Q: Am I affected by this vulnerability?

You are affected if your site runs e-Commerce Plugin. Versions below 2.12.7 are vulnerable; that release and later are not.

Q: How do I fix it?

Update e-Commerce Plugin to version 2.12.7 or later. That is the complete fix. Until you can update, Request / payload inspection (WAF) in Hack Halt ProSecure contains this class of attack at the request layer.

Q: What can an attacker actually do?

This is a Cross-Site Scripting (XSS) flaw. An attacker who exploits it can run script in a visitor's browser, stealing sessions or planting an administrator account.

Vulnerability CVE-2026-120597 PLUGIN e-commerce LOW

A vulnerability was identified in Welcart e-Commerce Plugin up to 2.12.6 on WordPress. This affects the function ESCOTT_MAIN::error_page_message of the file classes/paymentESCOTT.main.class.php. Such manipulation of the argument ResponseCd leads to cross site scripting. The attack can be launched remotely. The exploit is publicly available and might be used. Upgrading to version 2.12.7 mitigates this issue. It is recommended to upgrade the affected component. The value is now escaped with esc_html() before output. The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product.

What to do about this

Low priority Contained impact, or it needs privileges an attacker would rarely already hold.

Fix it

Update e-Commerce Plugin to 2.12.7 or later.

That is the complete fix. Everything below is what protects you in the meantime.

Cannot update today? Request / payload inspection (WAF) in Hack Halt ProSecure blocks this class of attack before WordPress processes the request.

Inspect request parameters and bodies for injection, traversal and file-inclusion payloads, and refuse the request rather than logging it.
