{"id":"CVE-2026-4084","state":"PUBLISHED","title":"fyyd podcast shortcodes <= 0.3.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'color' Shortcode Attribute","description":"The fyyd podcast shortcodes plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'fyyd-podcast', 'fyyd-episode', and 'fyyd' shortcodes in all versions up to, and including, 0.3.1. This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes such as 'color', 'podcast_id', and 'podcast_slug'. These attributes are directly concatenated into inline JavaScript within single-quoted string arguments without any escaping or sanitization, allowing an attacker to break out of the JavaScript string context. 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":"2026-03-21T03:26:41.913Z","updatedAt":"2026-04-08T16:48:14.209Z","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":["cbednarek fyyd podcast shortcodes"],"affected":[{"vendor":"cbednarek","product":"fyyd podcast shortcodes","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"0.3.1","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/3f9d57ae-b238-43db-8eee-ccab499b1cbc?source=cve","https://plugins.trac.wordpress.org/browser/fyyd-podcast-shortcodes/trunk/fyyd-podcast-shortcodes.php#L65","https://plugins.trac.wordpress.org/browser/fyyd-podcast-shortcodes/tags/0.3.1/fyyd-podcast-shortcodes.php#L65","https://plugins.trac.wordpress.org/browser/fyyd-podcast-shortcodes/trunk/fyyd-podcast-shortcodes.php#L48","https://plugins.trac.wordpress.org/browser/fyyd-podcast-shortcodes/tags/0.3.1/fyyd-podcast-shortcodes.php#L48","https://plugins.trac.wordpress.org/browser/fyyd-podcast-shortcodes/trunk/fyyd-podcast-shortcodes.php#L60","https://plugins.trac.wordpress.org/browser/fyyd-podcast-shortcodes/tags/0.3.1/fyyd-podcast-shortcodes.php#L60","https://plugins.trac.wordpress.org/browser/fyyd-podcast-shortcodes/trunk/fyyd-podcast-shortcodes.php#L100","https://plugins.trac.wordpress.org/browser/fyyd-podcast-shortcodes/tags/0.3.1/fyyd-podcast-shortcodes.php#L100","https://plugins.trac.wordpress.org/browser/fyyd-podcast-shortcodes/trunk/fyyd-podcast-shortcodes.php#L224","https://plugins.trac.wordpress.org/browser/fyyd-podcast-shortcodes/tags/0.3.1/fyyd-podcast-shortcodes.php#L224","https://plugins.trac.wordpress.org/browser/fyyd-podcast-shortcodes/trunk/fyyd-podcast-shortcodes.php#L141","https://plugins.trac.wordpress.org/browser/fyyd-podcast-shortcodes/tags/0.3.1/fyyd-podcast-shortcodes.php#L141"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/4xxx/CVE-2026-4084.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-4084","state":"PUBLISHED","datePublished":"2026-03-21T03:26:41.913Z","dateUpdated":"2026-04-08T16:48:14.209Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-03-12T20:48:55.644Z"},"containers":{"cna":{"title":"fyyd podcast shortcodes <= 0.3.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'color' Shortcode Attribute","descriptions":[{"lang":"en","value":"The fyyd podcast shortcodes plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'fyyd-podcast', 'fyyd-episode', and 'fyyd' shortcodes in all versions up to, and including, 0.3.1.
