{"cve":"CVE-2026-16776","nvd":{"published":"2026-10-10T06:16:42.043","modified":"2026-10-13T13:30:21.620","status":"Deferred","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","score":6.4},"cwes":["CWE-79"],"references":["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#L147","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#L71","https://plugins.trac.wordpress.org/changeset?reponame=&old=3620318%40mp3-music-player-by-sonaar&new=3620318%40mp3-music-player-by-sonaar"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:58:01.639778232+00:00"},"epss":{"cve":"CVE-2026-16776","score":0.00195,"percentile":0.09125,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
