Summary

The Express Payment For Stripe plugin for WordPress up to version 1.28.0 has a stored XSS vulnerability via the 'type' attribute of the [stripe-express] shortcode. The attribute value is concatenated into an HTML attribute without esc_attr(), allowing authenticated attackers with contributor-level access to inject arbitrary scripts.

Risk Assessment

The risk involves script execution in all visitors' browsers, including administrators, potentially leading to data theft or session hijacking.

Recommendation

Update the Express Payment For Stripe plugin to the latest version. If unavailable, temporarily disable the plugin and apply WAF rules to block malicious shortcode attributes.

Original NVD description (English source)

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.
