{"id":"CVE-2026-4086","state":"PUBLISHED","title":"WP Random Button <= 1.0 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'cat' Shortcode Attribute","description":"The WP Random Button plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'cat', 'nocat', and 'text' shortcode attributes of the 'wp_random_button' shortcode in all versions up to, and including, 1.0. 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.","publishedAt":"2026-03-21T03:26:32.836Z","updatedAt":"2026-04-08T16:34:53.414Z","severity":{"score":6.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["newbiesup WP Random Button"],"affected":[{"vendor":"newbiesup","product":"WP Random Button","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.0","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/0b9e11f5-5a05-4867-abd8-fb07c84a49b0?source=cve","https://plugins.trac.wordpress.org/browser/wp-random-button/trunk/wp-random-button.php#L46","https://plugins.trac.wordpress.org/browser/wp-random-button/tags/1.0/wp-random-button.php#L46","https://plugins.trac.wordpress.org/browser/wp-random-button/trunk/wp-random-button.php#L50","https://plugins.trac.wordpress.org/browser/wp-random-button/tags/1.0/wp-random-button.php#L50"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/4xxx/CVE-2026-4086.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-4086","state":"PUBLISHED","datePublished":"2026-03-21T03:26:32.836Z","dateUpdated":"2026-04-08T16:34:53.414Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-03-12T20:53:29.047Z"},"containers":{"cna":{"title":"WP Random Button <= 1.0 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'cat' Shortcode Attribute","descriptions":[{"lang":"en","value":"The WP Random Button plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'cat', 'nocat', and 'text' shortcode attributes of the 'wp_random_button' shortcode in all versions up to, and including, 1.0.
