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.","state":0,"publishedAt":"2026-10-10T05:30:58.432+00:00","modifiedAt":"2026-10-11T12:23:58.199+00:00","affected":[{"ecosystem":"Vendor product","name":"MP3 Audio Player – Music Player, Podcast Player & Radio by Sonaar","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"sonaar\",\n                    \"product\": \"MP3 Audio Player – Music Player, Podcast Player & Radio by Sonaar\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"5.14.2\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 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,"severity":"MEDIUM"}],"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"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-16776","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-16776","identifiers":["CVE-2026-16776"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
