{"schema":"threatline.record/2","record":{"id":"CVE-2026-16776","aliases":[],"summary":"MP3 Audio Player <= 5.14.2 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode Attributes","details":"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.","categories":["Unclassified"],"product":"MP3 Audio Player – Music Player, Podcast Player & Radio by Sonaar","vendor":"sonaar","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-16776","source_modified_at":"2026-10-11T12:23:58.199Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"MP3 Audio Player – Music Player, Podcast Player & Radio by Sonaar","vendor":"sonaar","versions":[{"version":"0","status":"affected","lessThanOrEqual":"5.14.2","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":6.4,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00201,"percentile":0.0948,"score_date":"2026-10-23"},"published_at":"2026-10-10T05:30:58.432Z","modified_at":"2026-10-11T12:23:58.199Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-16776","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-11T12:23:58.199Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-16776","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/5e4b0fa4-51b7-4892-9087-30618900e069?source=cve"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/mp3-music-player-by-sonaar/tags/5.13/includes/class-sonaar-music-widget.php#L1923"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/mp3-music-player-by-sonaar/tags/5.13/includes/class-sonaar-music-widget.php#L147"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/mp3-music-player-by-sonaar/tags/5.13/admin/class-sonaar-music-admin.php#L8672"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/mp3-music-player-by-sonaar/tags/5.13/includes/class-sonaar-music-widget.php#L71"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3620318%40mp3-music-player-by-sonaar&new=3620318%40mp3-music-player-by-sonaar"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3723825%40mp3-music-player-by-sonaar&new=3723825%40mp3-music-player-by-sonaar"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-11T12:17:03.203023Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-11T12:23:58.199Z","content_hash":"14fc57067461e2e48ccdf521d55398c085ee30dec80e8e23ab2ec6c8c33a0b4c"}}
