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."}],"title":"fyyd podcast shortcodes <= 0.3.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'color' Shortcode Attribute","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/3f9d57ae-b238-43db-8eee-ccab499b1cbc?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/fyyd-podcast-shortcodes/trunk/fyyd-podcast-shortcodes.php#L65"},{"url":"https://plugins.trac.wordpress.org/browser/fyyd-podcast-shortcodes/tags/0.3.1/fyyd-podcast-shortcodes.php#L65"},{"url":"https://plugins.trac.wordpress.org/browser/fyyd-podcast-shortcodes/trunk/fyyd-podcast-shortcodes.php#L48"},{"url":"https://plugins.trac.wordpress.org/browser/fyyd-podcast-shortcodes/tags/0.3.1/fyyd-podcast-shortcodes.php#L48"},{"url":"https://plugins.trac.wordpress.org/browser/fyyd-podcast-shortcodes/trunk/fyyd-podcast-shortcodes.php#L60"},{"url":"https://plugins.trac.wordpress.org/browser/fyyd-podcast-shortcodes/tags/0.3.1/fyyd-podcast-shortcodes.php#L60"},{"url":"https://plugins.trac.wordpress.org/browser/fyyd-podcast-shortcodes/trunk/fyyd-podcast-shortcodes.php#L100"},{"url":"https://plugins.trac.wordpress.org/browser/fyyd-podcast-shortcodes/tags/0.3.1/fyyd-podcast-shortcodes.php#L100"},{"url":"https://plugins.trac.wordpress.org/browser/fyyd-podcast-shortcodes/trunk/fyyd-podcast-shortcodes.php#L224"},{"url":"https://plugins.trac.wordpress.org/browser/fyyd-podcast-shortcodes/tags/0.3.1/fyyd-podcast-shortcodes.php#L224"},{"url":"https://plugins.trac.wordpress.org/browser/fyyd-podcast-shortcodes/trunk/fyyd-podcast-shortcodes.php#L141"},{"url":"https://plugins.trac.wordpress.org/browser/fyyd-podcast-shortcodes/tags/0.3.1/fyyd-podcast-shortcodes.php#L141"}],"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":"Muhammad Yudha - DJ"}],"timeline":[{"time":"2026-03-20T15:06:48.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-03-23T17:23:28.606505Z","id":"CVE-2026-4084","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":"2026-03-23T17:23:43.524Z"}}]}}
