{"id":"CVE-2026-16776","state":"PUBLISHED","title":"MP3 Audio Player <= 5.14.2 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode Attributes","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.","publishedAt":"2026-10-10T05:30:58.432Z","updatedAt":"2026-10-11T12:23:58.199Z","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":["sonaar MP3 Audio Player – Music Player, Podcast Player & Radio by Sonaar"],"affected":[{"vendor":"sonaar","product":"MP3 Audio Player – Music Player, Podcast Player & Radio by Sonaar","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"5.14.2","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/5e4b0fa4-51b7-4892-9087-30618900e069?source=cve","https://plugins.trac.wordpress.org/browser/mp3-music-player-by-sonaar/tags/5.13/includes/class-sonaar-music-widget.php#L1923","https://plugins.trac.wordpress.org/browser/mp3-music-player-by-sonaar/tags/5.13/includes/class-sonaar-music-widget.php#L147","https://plugins.trac.wordpress.org/browser/mp3-music-player-by-sonaar/tags/5.13/admin/class-sonaar-music-admin.php#L8672","https://plugins.trac.wordpress.org/browser/mp3-music-player-by-sonaar/tags/5.13/includes/class-sonaar-music-widget.php#L71","https://plugins.trac.wordpress.org/changeset?reponame=&old=3620318%40mp3-music-player-by-sonaar&new=3620318%40mp3-music-player-by-sonaar","https://plugins.trac.wordpress.org/changeset?reponame=&old=3723825%40mp3-music-player-by-sonaar&new=3723825%40mp3-music-player-by-sonaar"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:11:00.674Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/16xxx/CVE-2026-16776.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-16776","state":"PUBLISHED","datePublished":"2026-10-10T05:30:58.432Z","dateUpdated":"2026-10-11T12:23:58.199Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-07-23T17:10:44.290Z"},"containers":{"cna":{"title":"MP3 Audio Player <= 5.14.2 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode Attributes","descriptions":[{"lang":"en","value":"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.
