{"cve":"CVE-2026-4072","nvd":{"published":"2026-03-21T04:17:40.413","modified":"2026-06-17T10:55:56.620","status":"Deferred","description":"The WordPress PayPal Donation plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'donate' shortcode in all versions up to, and including, 1.01. This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes such as 'amount', 'email', 'title', 'return_url', 'cancel_url', 'ccode', and 'image'. The wordpress_paypal_donation_create() function uses extract(shortcode_atts(...)) to process shortcode attributes and then directly interpolates these values into HTML output within single-quoted attribute values without any escaping. 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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","score":6.4},"cwes":["CWE-79"],"references":["https://plugins.trac.wordpress.org/browser/wordpress-paypal-donation/tags/1.01/wp-paypal-donation.php#L260","https://plugins.trac.wordpress.org/browser/wordpress-paypal-donation/tags/1.01/wp-paypal-donation.php#L271","https://plugins.trac.wordpress.org/browser/wordpress-paypal-donation/trunk/wp-paypal-donation.php#L260","https://plugins.trac.wordpress.org/browser/wordpress-paypal-donation/trunk/wp-paypal-donation.php#L271","https://www.wordfence.com/threat-intel/vulnerabilities/id/99a8b48b-2967-4179-a0eb-626bbe273f03?source=cve"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-4072","score":0.00201,"percentile":0.09982,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
