CVE-2023-1469 – WP Express Checkout <= 2.2.8 - Authenticated (Admin+) Stored Cross-Site Scripting via pec_coupon[code]

https://notcve.org/view.php?id=CVE-2023-1469

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. • https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=2879453%40wp-express-checkout&new=2879453%40wp-express-checkout&sfp_email=&sfph_mail= https://www.wordfence.com/threat-intel/vulnerabilities/id/b35ee801-f04d-4b22-8238-053b02a6ee0c?source=cve • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
