CVE-2026-8893
Received Received - Intake
Stored XSS in Express Payment For Stripe WordPress Plugin

Publication date: 2026-06-06

Last updated on: 2026-06-06

Assigner: Wordfence

Description
The Express Payment For Stripe plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'type' attribute of the [stripe-express] shortcode in versions up to, and including, 1.28.0. This is due to insufficient input sanitization and output escaping on the shortcode attribute value, which is concatenated into an HTML attribute in the rendered output of the register_shortcode() function without being passed through esc_attr() or any other escaping function. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

How can this vulnerability impact me? :

This vulnerability can allow attackers with contributor-level access to inject arbitrary web scripts into pages. These scripts can execute in the context of users visiting those pages, potentially leading to theft of user credentials, session hijacking, defacement, or other malicious actions. Since the vulnerability requires authenticated access, it primarily impacts sites where users have contributor or higher privileges.


What immediate steps should I take to mitigate this vulnerability?

To mitigate this vulnerability, you should update the Express Payment For Stripe plugin for WordPress to a version later than 1.28.0 where the issue is fixed.

Additionally, restrict contributor-level access and above to trusted users only, as the vulnerability requires authenticated users with at least contributor privileges to exploit.

Review and sanitize any shortcode attributes in your WordPress pages to ensure no malicious scripts are injected.


Can you explain this vulnerability to me?

The Express Payment For Stripe plugin for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in versions up to and including 1.28.0. This vulnerability arises because the 'type' attribute of the [stripe-express] shortcode is not properly sanitized or escaped before being included in the HTML output. As a result, authenticated users with contributor-level access or higher can inject malicious scripts that will execute whenever someone views the affected page.
