{"id":"CVE-2026-16776","published":"2026-10-10T06:16:42.043","lastModified":"2026-10-13T13:30:21.620","description":"The MP3 Audio Player – Music Player, Podcast Player & Radio by Sonaar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Shortcode Attributes in all versions up to, and including, 5.14.2 due to insufficient input sanitization and output 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. WordPress's save-time wp_kses_post does not neutralize the payload because the attack is delivered via shortcode attributes rather than raw HTML in post content, allowing the unescaped values to survive to render time.","cvssScore":6.4,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","cwes":["CWE-79"],"vendors":[],"products":[],"references":[{"url":"https://plugins.trac.wordpress.org/browser/mp3-music-player-by-sonaar/tags/5.13/admin/class-sonaar-music-admin.php#L8672","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/mp3-music-player-by-sonaar/tags/5.13/includes/class-sonaar-music-widget.php#L147","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/mp3-music-player-by-sonaar/tags/5.13/includes/class-sonaar-music-widget.php#L1923","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/mp3-music-player-by-sonaar/tags/5.13/includes/class-sonaar-music-widget.php#L71","tags":[]},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3620318%40mp3-music-player-by-sonaar&new=3620318%40mp3-music-player-by-sonaar","tags":[]},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3723825%40mp3-music-player-by-sonaar&new=3723825%40mp3-music-player-by-sonaar","tags":[]},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/5e4b0fa4-51b7-4892-9087-30618900e069?source=cve","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
