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."}],"title":"WordPress PayPal Donation <= 1.01 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'amount' Shortcode Attribute","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/99a8b48b-2967-4179-a0eb-626bbe273f03?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/wordpress-paypal-donation/trunk/wp-paypal-donation.php#L271"},{"url":"https://plugins.trac.wordpress.org/browser/wordpress-paypal-donation/tags/1.01/wp-paypal-donation.php#L271"},{"url":"https://plugins.trac.wordpress.org/browser/wordpress-paypal-donation/trunk/wp-paypal-donation.php#L260"},{"url":"https://plugins.trac.wordpress.org/browser/wordpress-paypal-donation/tags/1.01/wp-paypal-donation.php#L260"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')","cweId":"CWE-79","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","baseScore":6.4,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"Gilang Asra Bilhadi"}],"timeline":[{"time":"2026-03-20T15:07:36.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-03-23T17:08:00.403230Z","id":"CVE-2026-4072","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-03-23T17:08:21.312Z"}}]}}
