CVE-2023-1469
Medium 4.4
In plain English
A medium-severity security flaw in WP Express Checkout (Accept PayPal Payments Easily) from mra13. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.4% (higher than 29% of all known vulnerabilities).
Official description
The WP Express Checkout plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘pec_coupon[code]’ parameter in versions up to, and including, 2.2.8 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers with administrator-level access to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Note: This can potentially be exploited by lower-privileged users if the `Admin Dashboard Access Permission` setting it set for those users to access the dashboard.
