This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes. Specifically, the random_button_html() function directly concatenates the 'cat' and 'nocat' parameters into HTML data-attributes without esc_attr(), and the 'text' parameter into HTML content without esc_html(). 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":"WP Random Button <= 1.0 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'cat' Shortcode Attribute","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/0b9e11f5-5a05-4867-abd8-fb07c84a49b0?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/wp-random-button/trunk/wp-random-button.php#L46"},{"url":"https://plugins.trac.wordpress.org/browser/wp-random-button/tags/1.0/wp-random-button.php#L46"},{"url":"https://plugins.trac.wordpress.org/browser/wp-random-button/trunk/wp-random-button.php#L50"},{"url":"https://plugins.trac.wordpress.org/browser/wp-random-button/tags/1.0/wp-random-button.php#L50"}],"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":"zakaria"}],"timeline":[{"time":"2026-03-20T15:06:00.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-03-23T18:17:33.400910Z","id":"CVE-2026-4086","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":"2026-03-23T18:18:10.629Z"}}]}}
